[vB4] Cancel load by additional.css

[xony]

Hello, I have modified the additional.css file a bit so that the icons that I don't need in cke_toolbar do not appear, so far so good.

But I want to do the same with the line break that the icons have, I add this to the additional.css, but it doesn't work for me:

I change this code:      .cke_skin_kama .cke_break{font-size:0;clear:left;}

for this but it doesn't work        .cke_skin_kama .cke_break {font-size: 0; clear: none;}

Thanks.
