IE10 makes progress by supporting HTML5

PanARMENIAN.Net - The Internet Explorer Blog introduces the second platform preview of IE10 which makes progress in this area by fully supporting the HTML5 parsing algorithm.

“The Web is better when developers can use the same markup and same code across different browsers with the same results. This continues work we started in previous releases to improve IE’s HTML parser to make more HTML “just work” in the same way across browsers. Some key examples include supporting SVG-in-HTML, supporting HTML5 semantic elements, preserving the structure of unknown elements, and improving whitespace handling. As a result of this work, most HTML parses the same across IE9 and other browsers,” IEBlog says.

This is possible because HTML5 is the first version of HTML to fully define HTML parsing rules, down to the last edge case and error condition. So the goal of this work is to ensure all HTML parses the same across modern browsers.

Even if developer’s markup is invalid, HTML5 still defines how to parse it and IE10 follows these rules. HTML5 ensures markup will parse consistently.

Because some features in earlier versions of IE aren’t compatible with HTML5 parsing, they removed them from IE10 mode. Sites that rely on these legacy features will still work when running in legacy modes. This way, sites that work today will continue to work with IE10 even if the developers of the site don’t have the time to update them.
