There were probably several before it, but Adobe’s CSS Advisor is one of the best resources to perfect your CSS skills available online. And in true Web 2.0 fashion, it’s in Beta.

What this resource offers is a wiki-like funtionality where stumped developers and designers can find postings about problems and solutions published by registered members. Workarounds for past cases help build the knowledge base on CSS.

Also, users can rate, comment and tag (yes, tag) posts on selected topics such as CSS properties and Browsers. (Speaking of browsers, IE accounts for 70% of the problems posted on the Browser section of the site.)

My concern about the site is that writing a post may be too cumbersome or too time-consuming, so a save or continue feature may be useful
All in all, web standardistas have a new place to go to and that’s Adobe’s CSS Advisor.
