Is your browser compatible with CSS Selectors?

CSS Selectors test-suite automatically runs a large number of small tests which will determine if your browser is compatible with a large number of CSS selectors. If it is not compatible with a particular selector it is marked as such. You can click on each CSS selector to see the results, including a small example and explanation for each of tests.
