While you could go over to the W3C and peruse its documentation, it’s always nice to see information being presented in a more user friendly way than dry specification documents. I know that CSS2.x adoption is still bumping along – IE comes to mind as a laggard – but CSS3 has some nice additions that I could use. One of these is border rounding, which is supported after a fashion by Firefox, Safari and Chrome (a very nice browser, even at this very early stage in its development; it’s Windows only for now so try out CrossOver Chromium if your OS preference is Linux or OS X). It would be very nice if CSS3 support was more advanced but that’s not how things are right now. Therefore, seeing a website like CSS3.Info with its latest CSS3 news and its previews, browser CSS selector testing among other things is a definite bonus.
