HTML5\u00a0is a\u00a0markup language<\/a>\u00a0used for structuring and presenting content on the\u00a0World Wide Web<\/a>. It is the fifth and final major\u00a0HTML<\/a>\u00a0version that is a\u00a0World Wide Web Consortium<\/a>\u00a0(W3C) recommendation. The current specification is known as the\u00a0HTML Living Standard<\/a>. It is maintained by the\u00a0Web Hypertext Application Technology Working Group<\/a>\u00a0(WHATWG), a consortium of the major browser vendors (Apple<\/a>,\u00a0Google<\/a>,\u00a0Mozilla<\/a>, and\u00a0Microsoft<\/a>).<\/p>\n

HTML5 was first released in a public-facing form on 22 January 2008, with a major update and \u201cW3C Recommendation\u201d status in October 2014. Its goals were to improve the language with support for the latest multimedia and other new features; to keep the language both easily readable by humans and consistently understood by computers and devices such as web browsers, parsers, etc., without XHTML\u2019s rigidity; and to remain backward-compatible with older software. HTML5 is intended to subsume not only HTML 4 but also XHTML 1 and DOM Level 2 HTML.<\/p>\n

HTML5 includes detailed processing models to encourage more interoperable implementations; it extends, improves, and rationalizes the markup available for documents and introduces markup and application programming interfaces (APIs) for complex web applications. For the same reasons, HTML5 is also a candidate for cross-platform mobile applications because it includes features designed with low-powered devices in mind.<\/p>\n

Many new syntactic features are included. To natively include and handle multimedia and graphical content, the new <video>, <audio> and <canvas> elements were added, expandable sections are natively implemented through <summary>\u2026<\/summary> and <details>\u2026<\/details> rather than depending on CSS or JavaScript, and support for scalable vector graphics (SVG) content and MathML for mathematical formulas was also added. To enrich the semantic content of documents, new page structure elements such as <main>, <section>, <article>, <header>, <footer>, <aside>, <nav>, and <figure> are added. New attributes were introduced, some elements and attributes were removed, and others such as <a>, <cite>, and <menu> were changed, redefined, or standardized. The APIs and Document Object Model (DOM) are now fundamental parts of the HTML5 specification, and HTML5 also better defines the processing for any invalid documents.<\/p>\n","protected":false},"excerpt":{"rendered":"
