Web platform
TheWeb platformis a collection of technologies developed asopen standardsby theWorld Wide Web Consortiumand other standardization bodies such as theWeb Hypertext Application Technology Working Group,theUnicode Consortium,theInternet Engineering Task Force,andEcma International.[1]It is theumbrella termintroduced by theWorld Wide Web Consortium,and in 2011 it was defined as "a platform for innovation, consolidation and cost efficiencies" by W3C CEO Jeff Jaffe.[2]Being built onThe evergreen Web(where rapid, automatic software updates, vendor co-operation, standardization, and competition take place) has allowed for the addition of new capabilities while addressing security and privacy risks. Additionally, developers are enabled to build interoperable content on a cohesive platform.[3]
The Web platform includes technologies—computer languagesandAPIs—that were originally created in relation to the publication ofWeb pages.This includesHTML,[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,andIRI.[6][7]
Platforms[edit]
HTML[edit]

HyperText Markup Language (HTML) is the standardmarkup languagefor documents designed to be displayed in aweb browser.It defines the content and structure ofweb content.It is often assisted by technologies such asCascading Style Sheets(CSS) andscripting languagessuch asJavaScript.
Web browsersreceive HTML documents from aweb serveror from local storage andrenderthe documents into multimedia web pages. HTML describes the structure of aweb pagesemanticallyand originally included cues for its appearance.
HTML elementsare the building blocks of HTML pages. With HTML constructs,imagesand other objects such asinteractive formsmay be embedded into the rendered page. HTML provides a means to createstructured documentsby denoting structuralsemanticsfor text such as headings, paragraphs, lists,links,quotes, and other items. HTML elements are delineated bytags,written usingangle brackets.Tags such as<img>and<input>directly introduce content into the page. Other tags such as<p>and</p>surround and provide information about document text and may include sub-element tags.Browsersdo not display the HTML tags but use them to interpret the content of the page.

Cascading Style Sheets(CSS) is a simple mechanism for adding style (e.g., fonts, colors, spacing) to Web documents.[9]
Scalable Vector Graphics[edit]
Scalable Vector Graphics (SVG) is anXML-basedvector image formatfor definingtwo-dimensionalgraphics, having support for interactivity and animation. The SVG specification is anopen standarddeveloped by theWorld Wide Web Consortiumsince 1999.
SVG images are defined in a vector graphics format and stored in XML text files. SVG images can thus bescaledin size without loss of quality, and SVG files can besearched,indexed,scripted,andcompressed.The XML text files can be created and edited withtext editorsorvector graphics editors,and are rendered by mostweb browsers.
Early adoption was limited due to lack of support in older versions of Internet Explorer. However, as of 2011, all major desktop browsers began to support SVG. Native browser support offers various advantages, such as not requiring plugins, allowing SVG to be mixed with other content, and improving rendering and scripting reliability. Mobile support for SVG exists in various forms, with different devices and browsers supporting SVG Tiny 1.1 or 1.2. SVG can be produced using vector graphics editors and rendered into raster formats. In web-based applications, Inline SVG allows embedding SVG content within HTML documents.
Despite its benefits, SVG can pose security risks if used for images, as it can host scripts or CSS, potentially leading to cross-site scripting attacks or other vulnerabilities.JavaScript[edit]
JavaScriptis the scripting language of the Web, enabling us to implement all kinds of powerful dynamic features. The usage of JavaScript is not limited to browsers. You can use it in server and console environments with Node.[10]
