The HTML5 standard has been given final approval by the World Wide Web Consortium (W3C) in a move that cements its position as a cornerstone of open web development.
HTML5 has been in use for many years, and many websites have adopted the technology to ensure that sites can adapt to the variety of device types and screen sizes on the market.
However, HTML5 has only now officially achieved 'Recommendation' status from the W3C.
W3C director Sir Tim Berners-Lee said that HTML5 is a vital standard for the future of the web, enabling numerous key features that many internet users take for granted.
"Today we think nothing of watching video and audio natively in the browser, and nothing of running a browser on a phone," he said.
"We expect to be able to share photos, shop, read the news, and look up information anywhere on any device. Though they remain invisible to most users, HTML5 and the Open Web Platform are driving these growing user expectations."
Jeff Jaffe, chief executive of the W3C, said that the organisation will now focus on other areas of open development to ensure the continued growth of a more open web that uses open standards.
"Now that HTML5 is done, W3C should focus on strengthening the parts of the Open Web Platform that developers most urgently need for success. I call this push for developers 'Application Foundations'," he said.
Jaffe explained that Application Foundations should focus on eight key areas deemed vital to the future of the web: Security and Privacy; Core Web Design and Development; Device Interaction; Application Lifecycle; Media and Real-Time Communications; Performance and Tuning; Usability and Accessibility; and Services.
Gumtree recently rebuilt its website on HTML5 to meet rising traffic levels from numerous different devices such as tablets, smartphones and desktops.
