CKEditor (formerly known as FCKeditor) is a WYSIWYG rich text editor which enables writing content directly inside of web pages or online applications. [2] [3] [4] [5] Its core code is written in JavaScript and it is developed by CKSource. CKEditor is available under open source and commercial licenses. [6]
The first version of CKEditor, under the name FCKeditor, was released in March 2003 by Frederico Caldeira Knabben, the creator of the editor and the project's Benevolent Dictator for Life. After reaching more than 3 million downloads,[ citation needed ] FCKeditor was completely reviewed and redesigned into CKEditor 3, with special attention given to performance, accessibility and a new UI. [7]
In December 2012, CKEditor 4 was released with an Inline Editing solution, reformatted source code, enhanced DOM and CSS performance. The server-side implementations were removed. Retired in June 2023. [8]
After five years, in 2018, CKEditor 5 first stable version was introduced. With its code rewritten from scratch, CKEditor 5 has a custom data model and architecture. The editor implements Operational Transformation for the tree-structured model as well as many other mechanisms which were required to create a real-time collaborative UX. [9]
CKEditor 5 is a JavaScript framework offering a rich API [10] to develop any editing solution. CKEditor 5 also offers builds, which are ready-to-use editors; there are currently 5 builds available to download: Classic, Inline, Balloon, Balloon block and Document. [11]
In October 2017, CKSource launched the CKEditor Ecosystem. As of 2023 it consists of the following products:
CKEditor 4 has features found in desktop word processors such as styles formatting (bold, italic, underline, bulleted and numbered lists), tables, block quoting, web resource linking, safe undo function, image inserting, paste from Word and other common HTML formatting tools. Also CKEditor 4 has built-in spell checker functionality provided as plug-ins by WebSpellChecker LLC. By default, it is available for free with a banner ad.[6] It checks the spelling of the text and marks all errors with a red wavy line and allows the user to choose one of the correct suggestions.
There are currently many plugins available with CKEditor 4 to serve different needs, e.g. CKFinder and Accessibility Checker (the CKSource's plugins). CKFinder is a file manager for including files and images within content created with the editors. It is compatible with both CKEditor 4 and 5 and is available under commercial license.
Accessibility Checker is available under both Open Source and commercial licenses.
CKEditor 5's architecture and custom data model makes it possible to enable real-time collaborative editing.
A custom collaborative solution can be built by using the CKEditor 5 Framework components and real-time collaborative editing can be enabled by connecting to the CKEditor Cloud Services.
A ready to use, drop-in component based on CKEditor 5 (Letters) offers a complete solution for real-time collaborative writing. [12]

Microsoft Silverlight is a discontinued application framework designed for writing and running rich internet applications, similar to Adobe's runtime, Adobe Flash. While early versions of Silverlight focused on streaming media, later versions supported multimedia, graphics, and animation, and gave support to developers for CLI languages and development tools. Silverlight was one of the two application development platforms for Windows Phone, but web pages using Silverlight did not run on the Windows Phone or Windows Mobile versions of Internet Explorer, as there was no Silverlight plugin for Internet Explorer on those platforms.
A browser toolbar is a toolbar that resides within a browser's window. All major web browsers provide support to browser toolbar development as a way to extend the browser's GUI and functionality. Browser toolbars are considered to be a particular kind of browser extensions that present a toolbar. Browser toolbars are specific to each browser, which means that a toolbar working on a browser does not work on another one. All browser toolbars must be installed in the corresponding browser before they can be used and require updates when new versions are released.
Web development tools allow web developers to test and debug their source code. They are different from website builders and integrated development environments (IDEs) in that they do not assist in the direct creation of a webpage, rather they are tools used for testing the user interface of a website or web application.

The HTML5 specification introduced the video element for the purpose of playing videos, partially replacing the object element. HTML5 video is intended by its creators to become the new standard way to show video on the web, instead of the previous de facto standard of using the proprietary Adobe Flash plugin, though early adoption was hampered by lack of agreement as to which video coding formats and audio coding formats should be supported in web browsers. As of 2020, HTML5 video is the only widely supported video playback technology in modern browsers, with the Flash plugin being phased out.
