H1 { elevation: 50rad; }
Here I have an error and a bug.
In first, angle are always convert in degree, and in this case, it should be not. In second, the validator said 50rad == 50deg, so this is a big bug.
a { text-align: "$"; }
The validator doesn't say "only for block-level elements". The bug comes from me. I know where it is but don't have time to find a solution.
Media are not supported at the moment. be careful !
