Is there a specific DOCTYPE i should be using to see CSS3 effects?
Not for CSS3 no, just a capable browser ;)
What danwellman said, and also.. http://www.quirksmode.org/compatibility.html
Check general browser compatibility for CSS3
Check your browser for CSS3 compatibility.
Im sure the browsers Im testing it in are all compatible. I'm trying to embed fonts into my CSS. But cant see it for some reason. Im working inside kentico CMS. Anything else that can cause the issue?
