Rule parser rejects 12px/1.5, a common syntax for font size / font height specification

[boutell]

My coworkers like to write:

12px/1.5

For the font size, which sets both the font size and the font height.

Unfortunately the CSS parser rejects this starting from the /.

It seems to be legal CSS syntax.

Writing

font: 12px/1.5

is indeed legal. I did not know that since I never used it. I will try to fix this.

I've not checked, but there might be a similar issue if a border-radius value includes the / character too.
