In computing, a theme is a preset package containing graphical appearance and functionality details. A theme usually comprises a set of shapes and colors for the graphical control elements, the window decoration and the window. Themes are used to customize the look and feel of a piece of computer software or of an operating system.
Also known as a skin (or visual style in Windows XP) [1] it is a custom graphical appearance preset package achieved by the use of a graphical user interface (GUI) that can be applied to specific computer software, operating system, and websites to suit the purpose, topic, or tastes of different users. As such, a skin can completely change the look and feel and navigation interface of a piece of application software or operating system.
Software that is capable of having a skin applied is referred to as being skinnable, and the process of writing or applying such a skin is known as skinning. Applying a skin changes a piece of software's look and feel—some skins merely make the program more aesthetically pleasing, but others can rearrange elements of the interface, potentially making the program easier to use.
Themes are often used to change the look and feel of a wide range of things at once, which makes them much less granular than allowing the user to set each option individually. For example, users might want the window-borders from a particular theme, but installing it would also alter the desktop background.
One method for dealing with this is to allow the user to select which parts of the theme they want to load; for example in Windows 98, users could load the background and screensaver from a theme, but leave the icons and sounds untouched.
In video games, the term "skin" is similarly used to refer to an in-game character or cosmetic options for a player's character and other in-game items, which can range from different color schemes, to more elaborate designs and costumes. Skins are often awarded as unlockable content for completing specific in-game goals or milestones. Skins can sometimes include historical incarnations of the player character (such as Insomniac Games' Spider-Man , which includes unlockable skins based on Spider-Man's past comic book and film appearances), [2] as well as crossovers with other video games (such as Final Fantasy XIII-2 offering a costume based on Ezio Auditore from the Assassin's Creed franchise, and Super Smash Bros. Ultimate offering costume items based on other video game characters for its customizable Mii Fighter characters). [3] [4] Fortnite Battle Royale has similarly featured extensive uses of licensed properties as the basis for skins, also including non-gaming properties such as comic book characters, [5] [6] the National Football League, [7] and musicians. [8]
Skins are sometimes distributed as part of downloadable content, and as pre-order incentives for newly-released games. In the 2010s, skins were increasingly deemed a virtual good as part of monetization strategies, especially within free-to-play games and those otherwise treated as a service. Via microtransactions commonly known as "loot boxes", a player can earn a random selection of in-game items, which may include skins and other cosmetic items of varying rarity. While often defended as being similar in practice to booster packs for collectible card games, researchers have deemed loot boxes to be "psychologically akin to gambling", [9] and their inclusion in full-priced games have faced criticism from players for being an anti-consumer practice. [10] [11] They have largely been supplanted by "battle passes", which are collections of in-game challenges and goals that unlock reward tiers over a short- or long-term period. [12]
Via the Steam platform, Counter-Strike: Global Offensive and Team Fortress 2 also allow players to trade these items, which has led to communities devoted to bartering them for real-world money, as well as gambling. [13] [14] [15] [16]
Firefox and Google Chrome either support or supported a form of theme. Firefox (and its sibling Thunderbird) supports themes either through lightweight themes (formerly Personas). [18] Google Chrome version 3.0 or later allows themes to alter the appearance of the browser. [19] Internet Explorer 5 and its immediate successor allowed the background picture of their toolbars to be customized. [20]
The most popular skins are for instant messaging clients, media center, and media player software, such as Trillian and Winamp, due to the association with fun that such programs try to encourage.
Some platforms support changing the standard interface, including most using the X Window System. For those that do not, programs can add the functionality, like WindowBlinds for Microsoft Windows and ShapeShifter for macOS.
Many websites are skinnable, particularly those that provide social capabilities. Some sites provide skins that make primarily cosmetic changes, while some—such as H2G2—offer skins that make major changes to page layout. As with standalone software interfaces, this is facilitated by the underlying technology of the website—XML and XSLT, for instance, facilitate major changes of layout, while CSS can easily produce different visual styles.
A graphical user interface, or GUI, is a form of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation. In many applications, GUIs are used instead of text-based UIs, which are based on typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on a computer keyboard.
In computing, a plug-in is a software component that adds a specific feature to an existing computer program. When a program supports plug-ins, it enables customization.
In user interface design, a pie menu or radial menu is a circular context menu where selection depends on direction. It is a graphical control element. A pie menu is made of several "pie slices" around an inactive center and works best with stylus input, and well with a mouse. Pie slices are drawn with a hole in the middle for an easy way to exit the menu.
A web browser is an application for accessing websites. When a user requests a web page from a particular website, the browser retrieves its files from a web server and then displays the page on the user's screen. Browsers are used on a range of devices, including desktops, laptops, tablets, and smartphones. By 2020, an estimated 4.9 billion people had used a browser. The most-used browser is Google Chrome, with a 67% global market share on all devices, followed by Safari with 18%.
In computing, a desktop environment (DE) is an implementation of the desktop metaphor made of a bundle of programs running on top of a computer operating system that share a common graphical user interface (GUI), sometimes described as a graphical shell. The desktop environment was seen mostly on personal computers until the rise of mobile computing. Desktop GUIs help the user to easily access and edit files, while they usually do not provide access to all of the features found in the underlying operating system. Instead, the traditional command-line interface (CLI) is still used when full control over the operating system is required.
In computing, cross-platform software is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms.
XUL, which stands for XML User Interface Language, is a user interface markup language developed by Mozilla. XUL is an XML dialect for writing graphical user interfaces, enabling developers to write user interface elements in a manner similar to web pages.
In computing, a windowing system is a software suite that manages separately different parts of display screens. It is a type of graphical user interface (GUI) which implements the WIMP paradigm for a user interface.
System software is software designed to provide a platform for other software. Examples of system software include operating systems (OS).
A favicon, also known as a shortcut icon, website icon, tab icon, URL icon, or bookmark icon, is a file containing one or more small icons associated with a particular website or web page. A web designer can create such an icon and upload it to a website by several means, and graphical web browsers will then make use of it. Browsers that provide favicon support typically display a page's favicon in the browser's address bar and next to the page's name in a list of bookmarks. Browsers that support a tabbed document interface typically show a page's favicon next to the page's title on the tab, and site-specific browsers use the favicon as a desktop icon.
The tooltip, also known as infotip or hint, is a common graphical user interface (GUI) element in which, when hovering over a screen element or component, a text box displays information about that element, such as a description of a button's function, what an abbreviation stands for, or the exact absolute time stamp over a relative time. In common practice, the tooltip is displayed continuously as long as the user hovers over the element or the text box provided by the tool. It is sometimes possible for the mouse to hover within the text box provided to activate a nested tooltip, and this can continue to any depth, often with multiple text boxes overlapped.

A mobile operating system is an operating system used for smartphones, tablets, smartwatches, smartglasses, or other non-laptop personal mobile computing devices. While computers such as typical/mobile laptops are "mobile", the operating systems used on them are usually not considered mobile, as they were originally designed for desktop computers that historically did not have or need specific mobile features. This "fine line" distinguishing mobile and other forms has become blurred in recent years, due to the fact that newer devices have become smaller and more mobile, unlike the hardware of the past. Key notabilities blurring this line are the introduction of tablet computers, light laptops, and the hybridization of the two in 2-in-1 PCs.
Google Chrome is a web browser developed by Google. It was first released in 2008 for Microsoft Windows, built with free software components from Apple WebKit and Mozilla Firefox. Versions were later released for Linux, macOS, iOS, iPadOS, and also for Android, where it is the default browser. The browser is also the main component of ChromeOS, where it serves as the platform for web applications.
A software widget is a relatively simple and easy-to-use software application or component made for one or more different software platforms.
Firefox was created by Dave Hyatt and Blake Ross as an experimental branch of the Mozilla browser, first released as Firefox 1.0 on November 9, 2004. Starting with version 5.0, a rapid release cycle was put into effect, resulting in a new major version release every six weeks. This was gradually accelerated further in late 2019, so that new major releases occur on four-week cycles starting in 2020.
Besides the Linux distributions designed for general-purpose use on desktops and servers, distributions may be specialized for different purposes including computer architecture support, embedded systems, stability, security, localization to a specific region or language, targeting of specific user groups, support for real-time applications, or commitment to a given desktop environment. Furthermore, some distributions deliberately include only free software. As of 2015, over four hundred Linux distributions are actively developed, with about a dozen distributions being most popular for general-purpose use.
The Xbox system software is the operating system developed exclusively for Microsoft's Xbox home video game consoles. Across the four generations of Xbox consoles, the software has been based on a version of Microsoft Windows and incorporating DirectX features optimized for the home consoles. The user interface, the Xbox Dashboard, provides access to games, media players, and applications, and integrates with the Xbox network for online functionality.
Comparison of user features of operating systems refers to a comparison of the general user features of major operating systems in a narrative format. It does not encompass a full exhaustive comparison or description of all technical details of all operating systems. It is a comparison of basic roles and the most prominent features. It also includes the most important features of the operating system's origins, historical development, and role.
