With Windows 10 Launch , Microsoft just retired from Internet Explorer by changing the default browser to Microsoft Edge .
To support CSS properties that have not yet been W3C standard in , browsers implement unique prefixes to support these new yet incomplete properties. Internet Explorer prefixes -ms-* .
Does Edge use these same prefixes, or has a new prefix been created for it (something like -ed-* for example)?
Just complementing the other answer, since 2014 Microsoft has worked harder to be able to display Web content in their browsers. And it has been observed that many pages, especially the mobile ones, have only used the prefix -webkit- and not others. Therefore, they have also considered properties that use the prefix -webkit- (source: The Mobile Web should just work for everyone ). This is even possible to see in the graph of the other answer.
Microsoft has also made available the Platform Status site that gives information about the development status of CSS resources.
Regarding the use of CSS prefixes, you should try to use all possible ( -webkit- , -ms- , -moz- , -o- ) and also, when possible, , as described in the Edge site .
To see more information about this, I wrote a post that addresses CSS prefixes in Edge .
Existing fixed prefixes that are extremely popular will remain until they have native support, but Microsoft Edge will not be introducing a new prefix system for features. Instead, they will use feature flags (such as Chrome and Firefox for experimental features on the client side rather than the developer side).
Microsoft still uses the -ms- * prefix. The styles supported by Edge are published in this link: link
You can see there are -ms- * and -webkit- * implemented in the engine.
