Disability |
---|
Web accessibility, or eAccessibility, [1] is the inclusive practice of ensuring there are no barriers that prevent interaction with, or access to, websites on the World Wide Web by people with physical disabilities, situational disabilities, and socio-economic restrictions on bandwidth and speed. When sites are correctly designed, developed and edited, more users have equal access to information and functionality.
For example, when a site is coded with semantically meaningful HTML, with textual equivalents provided for images and with links named meaningfully, this helps blind users using text-to-speech software and/or text-to-Braille hardware. When text and images are large and/or enlargeable, it is easier for users with poor sight to read and understand the content. When links are underlined (or otherwise differentiated) as well as colored, this ensures that color blind users will be able to notice them. When clickable links and areas are large, this helps users who cannot control a mouse with precision. When pages are not coded in a way that hinders navigation by means of the keyboard alone, or a single switch access device alone, this helps users who cannot use a mouse or even a standard keyboard. When videos are closed captioned, chaptered, or a sign language version is available, deaf and hard-of-hearing users can understand the video. When flashing effects are avoided or made optional, users prone to seizures caused by these effects are not put at risk. And when content is written in plain language and illustrated with instructional diagrams and animations, users with dyslexia and learning difficulties are better able to understand the content. When sites are correctly built and maintained, all of these users can be accommodated without decreasing the usability of the site for non-disabled users.
The needs that web accessibility aims to address include:
Accessibility is not confined to the list above, rather it extends to anyone who is experiencing any permanent, temporary or situational disability. Situational disability refers to someone who may be experiencing a boundary based on the current experience. For example, a person may be situationally one-handed if they are carrying a baby. Web accessibility should be mindful of users experiencing a wide variety of barriers. According to a 2018 WebAIM global survey of web accessibility practitioners, close to 93% of survey respondents received no formal schooling on web accessibility. [3]
Individuals living with a disability use assistive technologies such as the following to enable and assist web browsing:
In 1999 the Web Accessibility Initiative, a project by the World Wide Web Consortium (W3C), published the Web Content Accessibility Guidelines WCAG 1.0.
On 11 December 2008, the WAI released the WCAG 2.0 as a Recommendation. WCAG 2.0 aims to be up to date and more technology neutral. Though web designers can choose either standard to follow, the WCAG 2.0 have been widely accepted as the definitive guidelines on how to create accessible websites. Governments are steadily adopting the WCAG 2.0 as the accessibility standard for their own websites. [4] In 2012, the Web Content Accessibility Guidelines were also published as an ISO/IEC standard: "ISO/IEC 40500:2012: Information technology – W3C Web Content Accessibility Guidelines (WCAG) 2.0". [5] In 2018, the WAI released the WCAG 2.1 Recommendation that extends WCAG 2.0. [6]
There has been some criticism of the W3C process, claiming that it does not sufficiently put the user at the heart of the process. [7] There was a formal objection to WCAG's original claim that WCAG 2.0 will address requirements for people with learning disabilities and cognitive limitations headed by Lisa Seeman and signed by 40 organizations and people. [8] In articles such as "WCAG 2.0: The new W3C guidelines evaluated", [9] "To Hell with WCAG 2.0" [10] and "Testability Costs Too Much", [11] the WAI has been criticised for allowing WCAG 1.0 to get increasingly out of step with today's technologies and techniques for creating and consuming web content, for the slow pace of development of WCAG 2.0, for making the new guidelines difficult to navigate and understand, and other argued failings.
The accessibility of websites relies on the cooperation of several components: [12]
Web developers usually use authoring tools and evaluation tools to create web content.
People ("users") use web browsers, media players, assistive technologies or other "user agents" to get and interact with the content. [12]
Because of the growth in internet usage [18] and its growing importance in everyday life, countries around the world are addressing digital access issues through legislation. One approach is to protect access to websites for people with disabilities by using existing human or civil rights legislation. Some countries, like the U.S., protect access for people with disabilities through the technology procurement process. [19] It is common for nations to support and adopt the Web Content Accessibility Guidelines (WCAG) 2.0 by referring to the guidelines in their legislation. [20] [21] Compliance with web accessibility guidelines is a legal requirement primarily in North America, Europe, parts of South America and parts of Asia. [22]
Argentina
Law 26.653 on Accessibility to Information on Web Pages. [23] Approved by the National Congress of Argentina on November 3, 2010. It specifies in its Article 1 that both the National State and its decentralized organisms or those companies that are related in any way with public services or goods, must respect the rules and requirements on accessibility in the design of their web pages. The objective is to facilitate access to contents to all persons with disabilities, in order to guarantee equal opportunities in relation to access to information and to avoid discrimination.
In addition, by Decree 656/2019 [24] the regulation of the aforementioned Law No. 26,653 is approved and it is reported that the authority in charge of its application will be the ONTI, "Oficina Nacional de Tecnologías de Información" (National Office of Information Technologies). [25] This agency is in charge of assisting and/or advising the individuals and legal entities reached by this Law; in addition to disseminating, approving/updating and also controlling the fulfillment of the accessibility standards and requirements of the web pages; among other functions.
In 2000, an Australian blind man won a $20,000 court case against the Sydney Organising Committee of the Olympic Games (SOCOG). [26] This was the first successful case under Disability Discrimination Act 1992 because SOCOG had failed to make their official website, Sydney Olympic Games, adequately accessible to blind users. The Human Rights and Equal Opportunity Commission (HREOC) also published World Wide Web Access: Disability Discrimination Act Advisory Notes. [27] All Governments in Australia also have policies and guidelines that require accessible public websites.
In Brazil, the federal government published a paper with guidelines for accessibility on 18 January 2005, for public reviewing. On 14 December of the same year, the second version was published, including suggestions made to the first version of the paper. On 7 May 2007, the accessibility guidelines of the paper became compulsory to all federal websites. The current version of the paper, which follows the WCAG 2.0 guidelines, is named e-MAG, Modelo de Acessibilidade de Governo Eletrônico (Electronic Government Accessibility Model), and is maintained by Brazilian Ministry of Planning, Budget, and Management.
The paper can be viewed and downloaded at its official website. [28]
In 2011, the Government of Canada began phasing in the implementation of a new set of web standards that are aimed at ensuring government websites are accessible, usable, interoperable and optimized for mobile devices. These standards replace Common Look and Feel 2.0 (CLF 2.0) Standards for the Internet.
The first of these four standards, Standard on Web Accessibility [29] came into full effect on 31 July 2013. The Standard on Web Accessibility follows the Web Content Accessibility Guidelines (WCAG) 2.0 AA, and contains a list of exclusions that is updated annually. It is accompanied by an explicit Assessment Methodology [30] that helps government departments comply. The government also developed the Web Experience Toolkit (WET), [31] a set of reusable web components for building innovative websites. The WET helps government departments build innovative websites that are accessible, usable and interoperable and therefore comply with the government's standards. The WET toolkit is open source and available for anyone to use.
The three related web standards are: the Standard on Optimizing Websites and Applications for Mobile Devices, [32] the Standard on Web Usability [33] and the Standard on Web Interoperability. [34]
In 2019 the Government of Canada passed the Accessible Canada Act. This builds on the on provincial legislation like the Accessibility for Ontarians with Disabilities Act, The Accessibility for Manitobans Act and the Nova Scotia Accessibility Act.
In February 2014 a draft law was endorsed by the European Parliament stating that all websites managed by public sector bodies have to be made accessible to everyone. [35]
A European Commission Communication on eAccessibility was published on 13 September 2005. [1] The commission's aim to "harmonise and facilitate the public procurement of accessible ICT products and services" was embedded in a mandate issued to CEN, CENELEC and ETSI in December 2005, reference M 376. [36] A mandate is a request for the drafting and adoption of a European standard or European standardisation deliverables issued to one or more of the European standardisation organisations. Mandates are usually accepted by the standardisation organisation because they are based on preliminary consultation, although technically the organisation is independent and has a right to decline the mandate. [37] The mandate also called for the development of an electronic toolkit for public procurers enabling them to have access to the resulting harmonised requirements. [38] The commission also noted that the harmonised outcome, while intended for public procurement purposes, might also be useful for procurement in the private sector. [38] : Section 2.3
On 26 October 2016, the European Parliament approved the Web Accessibility Directive, which requires that the websites and mobile apps of public sector bodies be accessible. The relevant accessibility requirements are described in the European standard EN 301 549 V3.2.1 (published by ETSI). EU member states were expected to bring into force by 23 September 2018 laws and regulations that enforce the relevant accessibility requirements.
Some categories of websites and apps are excepted from the directive, for example "websites and mobile applications of public service broadcasters and their subsidiaries". [39]
The European Commission's "Rolling Plan for ICT Standardisation 2017" notes that ETSI standard EN 301 549 V1.1.2 will need to be updated to add accessibility requirements for mobile applications and evaluation methodologies to test compliance with the standard. [40]
In 2019 the European Union introduced the European Accessibility Act, as one of the leading pieces of legislation for digital accessibility and digital inclusion. The European Accessibility Act (EAA), which will enter into force on 28 June 2025, requiring companies to ensure that the newly marketed products and services covered by the Act are accessible. All websites will need to meet a minimum AA-level criterion. As of June 28, 2025, customers will be able to file complaints before national courts or authorities if services or products do not respect the new rules. [41]
In India, National Informatics Centre (NIC), under Ministry of Electronics and Information Technology (MeitY) has passed Guidelines for Indian Government Websites (GIGW) [42] for government agencies in 2009, compelling them to adhere to WCAG 2.0 Level A standards. [43]
Ministry of Electronics and Information Technology (MeitY) has National Policy on Universal Electronic Accessibility [44] clearly stated, Accessibility Standards and Guidelines be formulated or adapted from prevailing standards in the domain including World Wide Web Consortium accessibility Web standards and guidelines such as Authoring Tool Accessibility Guidelines (ATAG [45] ), Web Content Accessibility Guidelines (WCAG 2.0) and User Agent Accessibility Guidelines (UAAG [46] ).
GIGW aims to ensure the quality and accessibility of government guidelines by offering guidance on desirable practices covering the entire lifecycle of websites, web portals and web applications, right from conceptualization and design to their development, maintenance and management. The Department of Administrative Reforms and Public Grievances made the same a part of the Central Secretariat Manual of Office Procedure.
GIGW 3.0 [47] also significantly enhances the guidance on the accessibility and usability of mobile apps, especially by offering specific guidance to government organizations on how to leverage public digital infrastructure devised for whole-of-government delivery of services, benefits and information. [48]
The Rights of Persons with Disabilities Act, 2016 (RPwD) [49] passed in parliament. The law replaced earlier legislation and provided clearer guidance for digital accessibility. The RPwD Act, 106 through Sections 40-46 mandates accessibility to be ensured in all public-centric buildings, transportation systems, Information and Communication Technology (ICT) services, consumer products and all other services being provided by the Government or other service providers. [50]
In Ireland, the Disability Act 2005 [51] requires that where a public body communicates in electronic form with one or more persons, the contents of the communication must be, as far as practicable, "accessible to persons with a visual impairment to whom adaptive technology is available" (Section 28(2)). The National Disability Authority has produced a Code of Practice [52] giving guidance to public bodies on how to meet the obligations of the Act. This is an approved code of practice and its provisions have the force of legally binding statutory obligations. It states that a public body can achieve compliance with Section 28(2) by "reviewing existing practices for electronic communications in terms of accessibility against relevant guidelines and standards", giving the example of "Double A conformance with the Web Accessibility Initiative's (WAI) Web Content Accessibility Guidelines (WCAG)".
The Israeli Ministry of Justice recently published regulations requiring Internet websites to comply with Israeli standard 5568, which is based on the W3C Web Content Accessibility Guidelines 2.0. The main differences between the Israeli standard and the W3C standard concern the requirements to provide captions and texts for audio and video media. The Israeli standards are somewhat more lenient, reflecting the current technical difficulties in providing such captions and texts in Hebrew. [53]
In Italy, web accessibility is ruled by the so-called "Legge Stanca" (Stanca Act), formally Act n.4 of 9 January 2004, officially published on the Gazzetta Ufficiale on 17 January 2004. The original Stanca Act was based on the WCAG 1.0. On 20 March 2013 the standards required by the Stanca Act were updated to the WCAG 2.0.
Web Content Accessibility Guidelines in Japan were established in 2004 as JIS (Japanese Industrial Standards) X 8341-3. JIS X 8341-3 was revised in 2010 as JIS X 8341-3:2010 to encompass WCAG 2.0, and it was revised in 2016 as JIS X 8341-3:2016 to be identical standards with the international standard ISO/IEC 40500:2012. The Japanese organization WAIC (Web Accessibility Infrastructure Committee) has published the history and structure of JIS X 8341-3:2016. [54]
In Malta Web Content Accessibility assessments were carried out by the Foundation for Information Technology Accessibility (FITA) since 2003. [55] Until 2018, this was done in conformance with the requirements of the Equal Opportunities Act (2000) CAP 43 and applied WACG guidelines. [56] With the advent of the EU Web Accessibility Directive the Malta Communications Authority was charged with ensuring the accessibility of online resources owned by Maltese public entities. [57] FITA continues to provide ICT accessibility assessments to public and commercial entities, applying standard EN301549 and WCAG 2.1 as applicable. Therefore, both the Equal Opportunities Act anti-discrimination legislation and the transposed EU Web Accessibility Directive are applicable to the Maltese scenario.
In Norway, web accessibility is a legal obligation under the Act 20 June 2008 No 42 relating to a prohibition against discrimination on the basis of disability, also known as the Anti-discrimination Accessibility Act. The Act went into force in 2009, and the Ministry of Government Administration, Reform and Church Affairs [Fornyings-, administrasjons- og kirkedepartementet] published the Regulations for universal design of information and communication technology (ICT) solutions [Forskrift om universell utforming av informasjons- og kommunikasjonsteknologiske (IKT)-løsninger] in 2013. [58] The regulations require compliance with Web Content Accessibility Guidelines 2.0 (WCAG 2.0) / NS / ISO / IEC 40500: 2012, level A and AA with some exceptions. [59] [60] The Norwegian Agency for Public Management and eGovernment (Difi) is responsible for overseeing that ICT solutions aimed at the general public are in compliance with the legislative and regulatory requirements. [61]
As part of the Web Accessibility Initiatives in the Philippines, the government through the National Council for the Welfare of Disabled Persons (NCWDP) board approved the recommendation of forming an ad hoc or core group of webmasters that will help in the implementation of the Biwako Millennium Framework set by the UNESCAP.
The Philippines was also the place where the Interregional Seminar and Regional Demonstration Workshop on Accessible Information and Communications Technologies (ICT) to Persons with Disabilities was held where eleven countries from Asia – Pacific were represented. The Manila Accessible Information and Communications Technologies Design Recommendations was drafted and adopted in 2003.
In Spain, UNE 139803:2012 is the norm entrusted to regulate web accessibility. This standard is based on Web Content Accessibility Guidelines 2.0. [62]
In Sweden, Verva, the Swedish Administrative Development Agency is responsible for a set of guidelines for Swedish public sector web sites. Through the guidelines, web accessibility is presented as an integral part of the overall development process and not as a separate issue. The Swedish guidelines contain criteria which cover the entire life cycle of a website; from its conception to the publication of live web content. These criteria address several areas which should be considered, including:
An English translation was released in April 2008: Swedish National Guidelines for Public Sector Websites. [63] The translation is based on the latest version of Guidelines which was released in 2006. [64]
In the UK, the Equality Act 2010 does not refer explicitly to website accessibility, but makes it illegal to discriminate against people with disabilities. The Act applies to anyone providing a service; public, private and voluntary sectors. The Code of Practice: Rights of Access – Goods, Facilities, Services and Premises document [65] published by the government's Equality and Human Rights Commission to accompany the Act does refer explicitly to websites as one of the "services to the public" which should be considered covered by the Act.
In December 2010 the UK released the standard BS 8878:2010 Web accessibility. Code of practice . This standard effectively supersedes PAS 78 (pub. 2006). PAS 78, produced by the Disability Rights Commission and usable by disabled people. The standard has been designed to introduce non-technical professionals to improved accessibility, usability and user experience for disabled and older people. [66] It will be especially beneficial to anyone new to this subject as it gives guidance on process, rather than on technical and design issues. BS 8878 is consistent with the Equality Act 2010 [67] and is referenced in the UK government's e-Accessibility Action Plan as the basis of updated advice on developing accessible online services. It includes recommendations for:
BS 8878 is intended for anyone responsible for the policies covering web product creation within their organization, and governance against those policies. It additionally assists people responsible for promoting and supporting equality and inclusion initiatives within organizations and people involved in the procurement, creation or training of web products and content. A summary of BS 8878 [68] is available to help organisations better understand how the standard can help them embed accessibility and inclusive design in their business-as-usual processes.
On 28 May 2019, BS 8878 was superseded by ISO 30071-1, the international Standard that built on BS 8878 and expanded it for international use. A summary of how ISO 30071-1 relates to BS 8878 [69] is available to help organisations understand the new Standard.
On April 9, National Rail replaced its blue and white aesthetic with a black and white theme, which was criticized for not conforming to the Web Content Accessibility Guidelines. The company restored the blue and white theme and said it is investing in modernising its website in accords to the latest accessibility guidelines. [70]
In 2019 new accessibility regulations [71] [72] came into force setting a legal duty for public sector bodies to publish accessibility statements and make their websites accessible by 23 September 2020 [73] Accessibility statements include information about how the website was tested and the organisation's plan to fix any accessibility problems. Statements should be published and linked to on every page on the website. [74]
In the United States, Section 508 Amendment to the Rehabilitation Act of 1973 requires all Federal agencies' electronic and information technology to be accessible to those with disabilities. Both members of the public and federal employees have the right to access this technology, such as computer hardware and software, websites, phone systems, and copiers. [75] Also, Section 504 of the Rehabilitation Act prohibits discrimination on the basis of disability for entities receiving federal funds and has been cited in multiple lawsuits against organizations such as hospitals that receive federal funds through medicare/medicaid.
In addition, Title III of the Americans with Disabilities Act (ADA) prohibits discrimination on the basis of disability. There is some debate on the matter; multiple courts and the U.S. Department of Justice have taken the position that the ADA requires website and app operators and owners to take affirmative steps to make their websites and apps accessible to disabled persons and compatible with common assistive technologies such as the JAWS screen reader, while other courts have taken the position that the ADA does not apply online. The U.S. Department of Justice has endorsed the WCAG2.0AA standard as an appropriate standard for accessibility in multiple settlement agreements. [76]
Numerous lawsuits challenging websites and mobile apps on the basis of the ADA have been filed since 2017. These cases appears spurred by a 2017 case, Gil v. Winn Dixie Stores, in which a federal court in Florida ruled that Winn Dixie's website must be accessible. Around 800 cases related to web accessibility were filed in 2017, and over 2,200 were filed in 2018. Additionally, though the Justice Department had stated in 2010 that they would publish guidelines for web accessibility, they reversed this plan in 2017, also spurring legal action against inaccessible sites. [77]
A notable lawsuit related to the ADA was filed against Domino's Pizza by a blind user who could not use Domino's mobile app. At the federal district level, the court ruled in favor of Domino's as the Justice Department had not established the guidelines for accessibility, but this was appealed to the Ninth Circuit. The Ninth Circuit overruled the district court, ruling that because Domino's is a brick-and-mortar store, which must meet the ADA, and the mobile app an extension of their services, their app must also be compliant with the ADA. Domino's petitioned to the Supreme Court, backed by many other restaurants and retail chains, arguing that this decision impacts their Due Process since disabled customers have other, more accessible means to order. [77] In October 2019, the Supreme Court declined to hear the case, which effectively upheld the decision of the 9th Circuit Court and requires the case to be heard as it stands. [78] [79]
The number and cost of federal accessibility lawsuits has risen dramatically in the last few years. [80]
A growing number of organizations, companies and consultants offer website accessibility audits. These audits, a type of system testing, identify accessibility problems that exist within a website, and provide advice and guidance on the steps that need to be taken to correct these problems.
A range of methods are used to audit websites for accessibility:
Each of these methods has its strengths and weaknesses:
Ideally, a combination of methods should be used to assess the accessibility of a website.
Once an accessibility audit has been conducted, and accessibility errors have been identified, the errors will need to be remediated in order to ensure the site is compliant with accessibility errors. The traditional way of correcting an inaccessible site is to go back into the source code, reprogram the error, and then test to make sure the bug was fixed. If the website is not scheduled to be revised in the near future, that error (and others) would remain on the site for a lengthy period of time, possibly violating accessibility guidelines. Because this is a complicated process, many website owners choose to build accessibility into a new site design or re-launch, as it can be more efficient to develop the site to comply with accessibility guidelines, rather than to remediate errors later.
With the progress in AI technology, web accessibility has become more accessible. With 3rd party add-ons that leverage AI and machine learning, it is possible to offer changes to the website design without altering the source code. This way, a website can be accessible to different types of users without the need to adjust the website for every accessibility equipment. [82]
For a web page to be accessible all important semantics about the page's functionality must be available so that assistive technology can understand and process the content and adapt it for the user. However, as content becomes more and more complex, the standard HTML tags and attributes become inadequate in providing semantics reliably. Modern Web applications often apply scripts to elements to control their functionality and to enable them to act as a control or other dynamic component. These custom components or widgets do not provide a way to convey semantic information to the user agent. WAI-ARIA (Accessible Rich Internet Applications) is a specification [83] published by the World Wide Web Consortium that specifies how to increase the accessibility of dynamic content and user interface components developed with Ajax, HTML, JavaScript and related technologies. ARIA enables accessibility by enabling the author to provide all the semantics to fully describe its supported behaviour. It also allows each element to expose its current states and properties and its relationships between other elements. Accessibility problems with the focus and tab index are also corrected.
In 1998, the U.S. Congress amended the Rehabilitation Act to require federal agencies to make their electronic and information technology accessible to people with disabilities. Section 508 was enacted to eliminate barriers in information technology, to make available new opportunities for people with disabilities and to encourage the development of technologies that will help achieve these goals. The law applies to all federal agencies when they develop, procure, maintain, or use electronic and information technology. Under Section 508, agencies must give employees with disabilities and members of the public access to information that is comparable to the access available to others.
The World Wide Web is an information system that enables content sharing over the Internet through user-friendly ways meant to appeal to users beyond IT specialists and hobbyists. It allows documents and other web resources to be accessed over the Internet according to specific rules of the Hypertext Transfer Protocol (HTTP).
An HTML editor is a program used for editing HTML, the markup of a web page. Although the HTML markup in a web page can be controlled with any text editor, specialized HTML editors can offer convenience, added functionality, and organisation. For example, many HTML editors handle not only HTML, but also related technologies such as CSS, XML and JavaScript or ECMAScript. In some cases they also manage communication with remote web servers via FTP and WebDAV, and version control systems such as Subversion or Git. Many word processing, graphic design and page layout programs that are not dedicated to web design, such as Microsoft Word or Quark XPress, also have the ability to function as HTML editors.
The World Wide Web Consortium (W3C)'s Web Accessibility Initiative (WAI) is an effort to improve the accessibility of the World Wide Web for people with disabilities. People with disabilities encounter difficulties when using computers generally, but also on the Web. Since they often require non-standard devices and browsers, making websites more accessible also benefits a wide range of user agents and devices, including mobile devices, which have limited resources. According to a US government study, 71% of website visitors with disabilities will leave a website that is not accessible.
Accessibility is the design of products, devices, services, vehicles, or environments so as to be usable by people with disabilities. The concept of accessible design and practice of accessible development ensures both "direct access" and "indirect access" meaning compatibility with a person's assistive technology.
Computer accessibility refers to the accessibility of a computer system to all people, regardless of disability type or severity of impairment. The term accessibility is most often used in reference to specialized hardware or software, or a combination of both, designed to enable the use of a computer by a person with a disability or impairment.
Web standards are the formal, non-proprietary standards and other technical specifications that define and describe aspects of the World Wide Web. In recent years, the term has been more frequently associated with the trend of endorsing a set of standardized best practices for building web sites, and a philosophy of web design and development that includes those methods.
Web usability of a website consists of broad goals of usability, presentation of information, choices made in a clear and concise way, a lack of ambiguity and the placement of important items in appropriate areas as well as ensuring that the content works on various devices and browsers.
The alt attribute is the HTML attribute used in HTML and XHTML documents to specify alternative text that is to be displayed in place of an element that cannot be rendered. The alt attribute is used for short descriptions, with longer descriptions using the longdesc attribute. The standards organization for the World Wide Web, the World Wide Web Consortium (W3C), recommends that every image displayed through HTML have an alt attribute, though the alt attribute does not need to contain text. The lack of proper alt attributes on website images has led to several accessibility-related lawsuits.
PAS 78: Guide to good practice in commissioning accessible websites is a Publicly Available Specification published on March 8, 2006 by the British Standards Institution in collaboration with the Disability Rights Commission. It provides guidance to organisations in how to go about commissioning an accessible website from a design agency. It describes what is expected from websites to comply with the UK Disability Discrimination Act 1995, making websites accessible to disabled people.
The Web Content Accessibility Guidelines (WCAG) are part of a series of web accessibility guidelines published by the Web Accessibility Initiative (WAI) of the World Wide Web Consortium (W3C), the main international standards organization for the Internet. They are a set of recommendations for making Web content more accessible, primarily for people with disabilities—but also for all user agents, including highly limited devices, such as mobile phones. WCAG 2.0 was published in December 2008 and became an ISO standard, ISO/IEC 40500:2012 in October 2012. WCAG 2.2 became a W3C Recommendation on 5 October 2023.
PDF/UA, formally ISO 14289, is an International Organization for Standardization (ISO) standard for accessible PDF technology. A technical specification intended for developers implementing PDF writing and processing software, PDF/UA provides definitive terms and requirements for accessibility in PDF documents and applications. For those equipped with appropriate software, conformance with PDF/UA ensures accessibility for people with disabilities who use assistive technology such as screen readers, screen magnifiers, joysticks and other technologies to navigate and read electronic content.
india.gov.in is the Indian government’s web portal for citizens. It presents information resources and online services from government sources, accessible from a single point. It is also known as the National Portal of India.
Design for All in the context of information and communications technology (ICT) is the conscious and systematic effort to proactively apply principles, methods and tools to promote universal design in computer-related technologies, including Internet-based technologies, thus avoiding the need for a posteriori adaptations, or specialised design.
The Government of Canada's Common Look and Feel (CLF) Standards for the Internet governed the branding, usability & accessibility standards for its websites and web applications from 2000 - 2010. It comprised the following four parts, now rescinded:
Lisa Seeman is an inventor and an entrepreneur and has been instrumental in creating standards for interoperability and accessibility.
British Standard 8878 is a Web Accessibility Code of Practice which was published by the BSI Group. The standard was officially launched on 7 December 2010.
A Voluntary Product Accessibility Template (VPAT) is a template containing information regarding how an Information and communications technology product or service conforms with Section 508 of the Rehabilitation Act of 1973, as amended (29 U.S.C. § 794 (d)). Section 508 provides guidelines for rendering ICT accessible to, and therefore usable by, people with disabilities. The VPAT was originally designed as a tool for vendors to document product compliance to Section 508 and facilitate government market research on ICT with accessible features. Many people started to call the completed document a "VPAT" but the wider procurement community would prefer to call it a product Accessibility Conformance Report, or ACR. The distinction is that the VPAT is the incomplete form, and the ACR is the completed report using the VPAT template.
The Rights of Persons with Disabilities Act, 2016 is a disability law passed by the Parliament of India to fulfill its obligations under the United Nations Convention on the Rights of Persons with Disabilities, ratified by India in 2007.[1] The Act replaces the Persons with Disabilities Act, 1995.
EN 301 549 is a European standard for digital accessibility. It specifies requirements for information and communications technology to be accessible for people with disabilities.
