This page documents Blitz's scores on the "css" subsuite of the Web Platform Tests.

Note: As it does not have a JavaScript engine, Blitz can only run about 20% of the total subtests. In the numbers below, tests that Blitz can't run are ignored and percentages are relative to the number of tests run.
