Style Sheet (web Development)
A web style sheet is a form of separation of content and presentation for web design in which the markup (i.e., HTML or XHTML) of a webpage contains the page's semantic content and structure, but does not define its visual layout (style). Instead, the style is defined in an external style sheet file using a style sheet language such as CSS or XSLT. This design approach is identified as a "separation" because it largely supersedes the antecedent methodology in which a page's markup defined both style and structure. The philosophy underlying this methodology is a specific case of separation of concerns. Benefits Separation of style and content has advantages, but has only become practical after improvements in popular web browsers' CSS implementations. Speed Overall, users experience of a site utilising style sheets will generally be quicker than sites that don’t use the technology. ‘Overall’ as the first page will probably load more slowly – because the style sheet ...

Separation Of Content And Presentation
Separation of content and presentation (or separation of content and style) is the separation of concerns design principle as applied to the authoring and presentation of content. Under this principle, visual and design aspects (presentation and style) are separated from the core material and structure (content) of a document. A typical analogy used to explain this principle is the distinction between the human skeleton (as the structural component) and human flesh (as the visual component) which makes up the body's appearance. Common applications of this principle are seen in Web design (HTML vs. CSS) and document typesetting ( body vs. its preamble). Use in Web design This principle is not a rigid guideline, but serves more as best practice for keeping appearance and structure separate. In many cases, the design and development aspects of a project are performed by different people, so keeping both aspects separated ensures both initial production accountability and later main ...

Mozilla Firefox
Mozilla Firefox, or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. It uses the Gecko rendering engine to display web pages, which implements current and anticipated web standards. In November 2017, Firefox began incorporating new technology under the code name " Quantum" to promote parallelism and a more intuitive user interface. Firefox is available for Windows 7 and later versions, macOS, and Linux. Its unofficial ports are available for various Unix and Unix-like operating systems, including FreeBSD, OpenBSD, NetBSD, illumos, and Solaris Unix. It is also available for Android and iOS. However, as with all other iOS web browsers, the iOS version uses the WebKit layout engine instead of Gecko due to platform requirements. An optimized version is also available on the Amazon Fire TV as one of the two main browsers available with Amazon's Silk Browser. Firefox was created in 2002 u ...

Stylus (browser Extension)
Stylus is a user style manager forked from Stylish for Chrome in 2017 after Stylish was bought by the analytics company SimilarWeb. The objective was to "remove any and all analytics, and return to a more user-friendly UI." It restored the user interface of Stylish 1.5.2 and removed Google Analytics. Reception Martin Brinkmann reported in May 2017 that "Stylus works as expected". As of December 2020, Stylus had more than 400,000 users on Google Chrome and nearly 70,000 users on Firefox. At that same time, it had an average rating of 4.6 stars on the Chrome Web Store and 4.5 stars on Firefox Add-ons.

Stylish
Stylish is a user style manager that can change the appearance of web pages in a user's browser without changing their content by including user-supplied CSS style sheets with those supplied by the web site itself. The Stylish browser extension includes tools with which to write user styles, and can install user styles written by other Stylish users from a companion website. These user styles may be more or less selective, targeting just one web page, or all of the pages on a domain, or every page on the web. Stylish was originally developed by Jason Barnabe as an XUL/XPCOM add-on for Mozilla Firefox. A Chrome extension followed in 2010, which was released for Blink-based Opera 15 in 2013 and as a Firefox WebExtension in 2017. Similar extensions for Safari and for Presto-based Opera are distributed as 'Stylish' by other developers with Barnabe's approval.

Refreshable Braille Display
A refreshable braille display or braille terminal is an electro-mechanical device for displaying braille characters, usually by means of round-tipped pins raised through holes in a flat surface. Visually impaired computer users who cannot use a standard computer monitor can use it to read text output. Deafblind computer users may also use refreshable braille displays. Speech synthesizers are also commonly used for the same task, and a blind user may switch between the two systems or use both at the same time depending on circumstances. Mechanical details The base of a refreshable braille display often integrates a pure braille keyboard. Similar to the Perkins Brailler, the input is performed by two sets of four keys on each side, while output is via a refreshable braille display consisting of a row of electro-mechanical character cells, each of which can raise or lower a combination of eight round-tipped pins. Other variants exist that use a conventional QWERTY keyboard for i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

User Agent
In computing, a user agent is any software, acting on behalf of a user, which "retrieves, renders and facilitates end-user interaction with Web content". A user agent is therefore a special kind of software agent. Some prominent examples of user agents are web browsers and email readers. Often, a user agent acts as the client in a client–server system. In some contexts, such as within the Session Initiation Protocol (SIP), the term ''user agent'' refers to both end points of a communications session. User agent identification When a software agent operates in a network protocol, it often identifies itself, its application type, operating system, device model, software vendor, or software revision, by submitting a characteristic identification string to its operating peer. In HTTP, SIP,RFC 3261, ''SIP: Session Initiation Protocol'', IETF, The Internet Society (2002) and NNTP protocols, this identification is transmitted in a header field ''User-Agent''. Bots, such as Web ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lynx (browser)
A lynx (; plural lynx or lynxes) is any of the four species (the Canada lynx, Iberian lynx, Eurasian lynx, or bobcat) within the medium-sized wild cat genus ''Lynx''. The name ''lynx'' originated in Middle English via Latin from the Greek word λύγξ, derived from the Indo-European root ''leuk-'' ('light, brightness') in reference to the luminescence of its reflective eyes. Appearance Lynx have a short tail, characteristic tufts of black hair on the tips of their ears, large, padded paws for walking on snow and long whiskers on the face. Under their neck, they have a ruff, which has black bars resembling a bow tie, although this is often not visible. Body colour varies from medium brown to goldish to beige-white, and is occasionally marked with dark brown spots, especially on the limbs. All species of lynx have white fur on their chests, bellies and on the insides of their legs, fur which is an extension of the chest and belly fur. The lynx's colouri ...

Fault-tolerant System
Fault tolerance is the property that enables a system to continue operating properly in the event of the failure of one or more faults within some of its components. If its operating quality decreases at all, the decrease is proportional to the severity of the failure, as compared to a naively designed system, in which even a small failure can cause total breakdown. Fault tolerance is particularly sought after in high-availability, mission-critical, or even life-critical systems. The ability of maintaining functionality when portions of a system break down is referred to as graceful degradation. A fault-tolerant design enables a system to continue its intended operation, possibly at a reduced level, rather than failing completely, when some part of the system fails. The term is most commonly used to describe computer systems designed to continue more or less fully operational with, perhaps, a reduction in throughput or an increase in response time in the event of some partial ...

Safari (web Browser)
Safari is a web browser developed by Apple. It is built into macOS, iOS, and iPadOS, and uses Apple's open-source browser engine, WebKit, which was derived from KHTML. Safari was introduced in Mac OS X Panther in January 2003. It was included with the iPhone since the latter's first generation, which came out in 2007. At that time, Safari was the fastest browser on the Mac. Between 2007 and 2012, Apple maintained a Windows version, but abandoned it due to low market share. In 2010, Safari 5 introduced a reader mode, extensions, and developer tools. Safari 11, released in 2017, added Intelligent Tracking Prevention, which uses artificial intelligence to block web tracking. Safari 13 added support Apple Pay, and authentication with FIDO2 security keys. Its interface was redesigned in Safari 15. In May 2022, Safari became the third most popular desktop browser after being overtaken by Microsoft Edge. Safari was then used by 9.61 percent of desktop computers worldwide. ...

Opera (web Browser)
Opera is a multi-platform web browser developed by its namesake company Opera. The browser is based on Chromium, but distinguishes itself from other Chromium-based browsers (Chrome, Edge, etc.) through its user interface and other features. Opera was initially released on 10 April 1995, making it one of the oldest desktop web browsers still actively developed. It was commercial software for its first ten years and had its own proprietary layout engine, Presto. In 2013, it switched from the Presto engine to Chromium. Opera is available on Windows, macOS, Linux, Android, and iOS (Safari WebKit engine). There are also mobile versions called Opera Mobile and Opera Mini. Opera users also have access to Opera News, a news app based on an AI platform. The company released a gaming-oriented version of the browser, Opera GX, in 2019, and a blockchain-focused Opera Crypto Browser into public beta in January 2022.

Internet Explorer
Internet Explorer (formerly Microsoft Internet Explorer and Windows Internet Explorer, commonly abbreviated IE or MSIE) is a series of graphical user interface, graphical web browsers developed by Microsoft which was used in the Microsoft Windows, Windows line of operating systems (in Windows 11, Windows Server Insider Build 22463 and Windows Server Insider Build 25110, it is replaced by the Chromium (web browser), Chromium version of Microsoft Edge). Starting in 1995, It was first released as part of the add-on package Microsoft Plus!, Plus! for Windows 95 that year. Later versions were available as free downloads, or in-service packs, and included in the original equipment manufacturer (OEM) service releases of Windows 95 and later versions of Windows. Microsoft spent over per year on Internet Explorer in the late 1990s, with over 1,000 people involved in the project by 1999. New feature development for the browser was discontinued in 2016 in favor of new browser Microsoft Ed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Web Design
Web design encompasses many different skills and disciplines in the production and maintenance of websites. The different areas of web design include web graphic design; user interface design (UI design); authoring, including standardised code and proprietary software; user experience design (UX design); and search engine optimization. Often many individuals will work in teams covering different aspects of the design process, although some designers will cover them all. The term "web design" is normally used to describe the design process relating to the front-end (client side) design of a website including writing markup. Web design partially overlaps web engineering in the broader scope of web development. Web designers are expected to have an awareness of usability and be up to date with web accessibility guidelines. History 1988–2001 Although web design has a fairly recent history, it can be linked to other areas such as graphic design, user experience, and multimedi ...
