Scalable Vector Graphics (SVG) is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation.
The SVG specification is an open standard developed by the World Wide Web Consortium (W3C) since 1999. SVG images and their behaviors are defined in XML text files. This means that they can be searched, indexed, scripted, and compressed. As XML files, SVG images can be created and edited with any text editor, but are more often created with drawing software. Comparison of layout engines (Scalable Vector Graphics) The following tables compare SVG compatibility and support for a number of layout engines.

Wikipedia's favicon, shown in an older version of Firefox (from 2008) History In March 1999, Microsoft released Internet Explorer 5, which supported favicons for the first time. Originally, the favicon was a file called favicon.ico placed in the root directory (e.g., of a web site.
It was used in Internet Explorer's favorites (bookmarks) and next to the URL in the address bar if the page was bookmarked. A side effect was that the number of visitors who have bookmarked the page could be estimated by the requests of the favicon. This side effect no longer works, as all modern browsers load the favicon file to display in their web address bar, regardless of whether the site is bookmarked. Ajax (programming) Ajax is not a single technology, but a group of technologies.
W3C Document Object Model. What's new?
20090106: The WebApps WG Drives DOM Specifications. The W3C Web Applications Working Group has taken over responsibility for the Document Object Model specifications, including a new revision of DOM Level 3 Events, a new DOM Core specification, and potentially any errata on older DOM specifications. Discussion can be directed to either the email@example.com or the firstname.lastname@example.org mailing lists. 20080122: The Document Object Model Activity is closed. The Document Object Model Working Group was closed in the Spring of 2004, after the completion of the DOM Level 3 Recommendations. Document Object Model. Hierarchy of objects in an example HTML DOM—Document Object Model Legacy DOM Intermediate DOM In 1997, Netscape and Microsoft released version 4.0 of Netscape Navigator and Internet Explorer respectively, adding support for Dynamic HTML (DHTML), functionality enabling changes to a loaded HTML document.
XMLHttpRequest Level 2. Abstract The XMLHttpRequest specification defines an API that provides scripted client functionality for transferring data between a client and a server.
It is used to send HTTP or HTTPS requests to a web server and load the server response data back into the script. Development versions of all major browsers support URI schemes beyond http: and https:, in particular, blob: URLs are supported. XMLHttpRequest is subject to the browser's same-origin policy: for security reasons, requests will only succeed if they are made to the same server that served the original web page. History and support Same origin policy. This mechanism bears a particular significance for modern web applications that extensively depend on HTTP cookies to maintain authenticated user sessions, as servers act based on the HTTP cookie information to reveal sensitive information or take state-changing actions. A strict separation between content provided by unrelated sites must be maintained on the client side to prevent the loss of data confidentiality or integrity.
 Web browser. A web browser (commonly referred to as a browser) is a software application for retrieving, presenting and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI/URL) and may be a web page, image, video or other piece of content. Hyperlinks present in resources enable users easily to navigate their browsers to related resources. Although browsers are primarily intended to use the World Wide Web, they can also be used to access information provided by web servers in private networks or files in file systems.
History The first web browser was invented in 1990 by Sir Tim Berners-Lee. It was called WorldWideWeb and was later renamed Nexus. The first commonly available web browser with a graphical user interface was Erwise. Microsoft responded with its Internet Explorer in 1995, also heavily influenced by Mosaic, initiating the industry's first browser war. Web browser engine.
