CSS Support Charts
These charts detail browser support for the CSS1 specification as well as portions of CSS2. The material focuses on browsers with versions released in 2000 and later, although there is an historical (pre-2000) CSS1 support chart also available.
These references are intended to help you determine which properties and values are supported or not in each browser. They are not meant to the definitive references for the full behavior of these properties or values, nor can they capture all of the nuances of partial support (where it exists). For more information, please consult Microsoft's MSDN and mozilla.org's Web Developer Documentation.
Note that these charts are generated by running browsers through test pages such as the W3C's CSS1 Test Suite and relying on various other sources. They therefore rely to a degree on human judgment and interpretation.
A key to the chart data is available.
