Microsoft has opened an online developer lab to allow developers to test emerging web standards and address problems of interoperability with HTML5.
Microsoft's latest Internet Explorer browser, IE9, is currently in beta and offers hardware-accelerated HTML 5.0 to speed up access to web pages. HTML5 Labs will allow developers to work with draft specifications of HTML5-based technologies from the W3C without building them into IE9.
The company said it "aims to give developers a stable foundation to build their experience on Internet Explorer 9 (IE9) knowing that their sites will continue to work with build updates".
Microsoft added that its rivals are implementing specifications too early, putting developers at risk of creating sites that appear inconsistently across browsers. This requires additional development cycles.
Ian Moulster, Microsoft's IE9 product manager, told Computer Weekly, "The problem with HTML5 is that the standards continually evolve. If you put unstable standards into a browser, and the developers write code which make use of standards in flux, when the standards change, the sites will no longer work."
"We're taking unrefined standards and putting them as separate modules for devs to work with. They're never built into product itself so there's less risk for developers," he added.
A recent report found Microsoft's share of the worldwide internet browser market fell below 50%, a fall of 9% since last year.
