[Solved -7 Answers] CSS – Targeting only Firefox with CSS

PROBLEM:

• Using conditional comments it is easy to target Internet Explorer with browser-specific CSS rules:

[pastacode lang=”css” manual=”%3C!–%5Bif%20IE%206%5D%3E%0A…include%20IE6-specific%20stylesheet%20here…%0A%3C!%5Bendif%5D–%3E%0A” message=”css code” highlight=”” provider=”manual”/]

• Sometimes it is the Gecko engine (Firefox) that misbehaves. What would be best way to target only Firefox with your CSS rules and not a single other browser? That is, not only should Internet Explorer ignore the Firefox-only rules, but also WebKit and Opera should.
