Moving the Stable Web Forward in IE10 Release Preview – IEBlog – Site Home – MSDN Blogs.

Say whaaat?

As part of Windows 8 Release Preview planning, we reviewed all the W3C draft standards supported by IE10. In particular, we looked for those specifications that:

• Are stable, that is, there were no recent additions or changes and no renaming or major changes are expected;
• Are supported by at least two browsers other than IE10;
• Are interoperable across all these browsers for the features’ core use cases;
• Are already used on the Web, including in their unprefixed form; and
• Reached Candidate Recommendation since Windows 8 Consumer Preview or are likely to become Candidate Recommendations in 2012.

The following W3C draft standard features match these criteria and IE10 now supports them in their unprefixed form:

• Gradients (CSS Image Values and Replaced Content)
• CSS Animations
• CSS Transitions
• CSS Transforms
• font-feature-settings property (CSS Fonts)
• Indexed Database API
• Timing control for script-based animations (requestAnimationFrame)

For compatibility with sites and apps developed using the Windows 8 Consumer Preview, IE10 also supports these standards in their vendor-prefixed form using the Microsoft vendor prefixes (‑ms‑/ms).

IE10 also supports the following W3C draft standards in vendor-prefixed form. We believe these drafts do not yet meet the criteria listed above:

• CSS Flexible Box Layout
• CSS Grid Layout
• CSS Regions
• CSS Exclusions and Shapes
• CSS Device Adaptation
