How to check css file compatibility?

Question

I am looking for an easy way to check if a given css file uses functions that are not compatible with a particular browser.

Something like a combination of the W3C CSS validator and caniuse.com database.

Any suggestions?

If you are looking for a tool to report them,

I am using Sublime Text with a plugin called SublimeLinter-csslint. it gives a yellow square around the code (warning) and a description below.

I'm not sure that it checks everything, but it works pretty well. Especially with EI capabilities.

I also found this plugin https://packagecontrol.io/packages/W3CValidators (they don’t use it, but I think it will work too)
