Unexpected token '6ch' (CSS3 relative length units)

E.g.: width:6ch.

Which browsers support ch right now? It looks like webkit does not.

Firefox supports ch since 3.5 and rem since 3.6. Chrome supports rem since 5. And Opera currently supports neither.

ex is supported by all 3.

Since this is fixed in the parser, could this bug be re-opened here.

I strongly suspect that anyone usinf ch as a value are not doing so by mistake. (At least I'm not.)

CSS lint is already using the latest parser with the fix. The parser officially supports relative units now. The warning you're seeing is a validation error, which is different. If there is a behavior that you don't think is correct, please open another issue.
