Internet Explorer compatibility cookbook
The Windows Internet Explorer Compatibility Cookbook describes changes that might impact websites and apps developed for (or with) earlier versions of Internet Explorer. Many changes help Internet Explorer comply more closely with broader industry standards while other changes improve performance, security, and reliability.
The Developer Guides generally tell you about the features new to Internet Explorer; here's where you'll learn what's changed and what may require you to update your code.
Note You might be able to use legacy document modes to emulate the behavior of earlier versions. If you do this, keep in mind it's a temporary solution at best. Starting with Internet Explorer 11, document modes are considered deprecated and might not be supported in any future versions of the browser. For best results, update your sites and apps to use features and techniques supported by industry standards and multiple browsers.
Be sure to check back from time to time as we plan to update this with new info and respond to your feedback.
