With so much going on with CSS3 it’s sometimes difficult to remember whether or not a specific browser (or specific version of a specific browser) supports a particular feature of CSS3.
Instead of wrestling through docs, something like The CSS3 Test might save you a few minutes here or there. By simply visiting the site in your target browser, you get a nicely organized and color coded outline of the supported CSS3 features.
I just ran the test in Chrome and scored 62% which is a bit surprising to me. As per the note on the site, the tests simply check to see what the browser recognizes, it doesn’t test how anything is implemented, unlike The Acid Test.
