Css-what kinds of "IF" statements there are?

Question

I'm dealing with crossbrowser issues... So I׳m looking for the best and clean CSS One of the most important issues is the "IF" statements for each browser

Answer 1

CSS, in and of itself, does not have "if statements".

Internet Explorer browsers do have conditional comments which provide a simple way to deliver code (HTML, CSS or JavaScript) to different versions of IE.

Other browsers don't really have anything like that, though there are browser vendor specific declarations like -moz-border-radius and -webkit-border-radius.

Answer 2

Take a look at this page:
