Additionally, developers are enabled to build interoperable content on a cohesive platform.[3] The Web platform includes technologies—computer languages and APIs—that were originally created in relation to the publication of Web pages. This includes HTML,[4] CSS, SVG, MathML,[5] WAI-ARIA, ECMAScript, WebGL, Web Storage, Indexed Database API, Web Components, WebAssembly, WebGPU, Web Workers, WebSocket, Geolocation API, Server-Sent Events, DOM Events, Media Fragments, XMLHttpRequest, Cross-Origin Resource Sharing, File API, RDFa, WOFF, HTTP, TLS 1.2, and IRI.[6][7] Platforms [edit] HTML [edit] This section is an excerpt from HTML.[edit] HTML HTML and variants Dynamic HTML HTML5 XHTML Basic Mobile Profile HTML elements and attributes HTML element article audio blink canvas div and span marquee meta video HTML attribute alt attribute HTML frame Editing HTML editor Text editor Character encodings and language Character encodings Character entity references (named characters) Unicode Language code Document and browser models Document Object Model Browser Object Model Style sheets CSS Font family Web colors Client-side scripting and APIs JavaScript WebCL HTMX Graphics and Web3D technology Web3D WebGL WebGPU WebXR W3C Validator WHATWG Quirks mode Web storage Rendering engine Comparisons Document markup languages Comparison of browser engines v t e Hypertext Markup Language (HTML) is the standard markup language[a] for documents designed to be displayed in a web browser. It defines the content and structure of web content. It is often assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript. Web browsers receive HTML documents from a web server or from local storage and render the documents into multimedia web pages. HTML describes the structure of a web page semantically and originally included cues for its appearance. HTML elements are the building blocks of HTML pages. With HTML constructs, images and other objects such as interactive forms may be embedded into the rendered page. HTML provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists, links, quotes, and other items. HTML elements are delineated by tags, written using angle brackets. Tags such as "}}'><img> and "}}'><input> directly introduce content into the page. Other tags such as "}}'><p> and its corresponding closing tag "}}'></p> surround and provide information about document text and may include sub-element tags. Browsers do not display the HTML tags, but use them to interpret the content of the page. HTML can embed programs written in a scripting language such as JavaScript, which affects the behavior and content of web pages. The inclusion of CSS defines the look and layout of content. The World Wide Web Consortium (W3C), former maintainer of the HTML and current maintainer of the CSS standards, has encouraged the use of CSS over explicit presentational HTML since 1997.[update][9] A form of HTML, known as HTML5, is used to display video and audio, primarily using the "}}'><canvas> element, together with JavaScript. CSS [edit] Cascading Style Sheets (CSS) is a simple mechanism for adding style (e.g., fonts, colors, spacing) to Web documents.[10] Scalable Vector Graphics [edit] This section is an excerpt from SVG.[edit] Scalable Vector Graphics sXBL SVG Working Group SVG filter effects Precision Graphics Markup Language Vector Markup Language XHTML+MathML+SVG SVG animation v t e Scalable Vector Graphics (SVG) is an XML-based vector graphics format for defining two-dimensional graphics, having support for interactivity and animation. The SVG specification is an open standard developed by the World Wide Web Consortium since 1999. SVG images are defined in a vector graphics format and stored in XML text files. SVG images can thus be scaled in size without loss of quality, and SVG files can be searched, indexed, scripted, and compressed. The XML text files can be created and edited with text editors or vector graphics editors, and are rendered by most web browsers. SVG can include JavaScript, potentially leading to cross-site scripting.
