Ok so I've got this line of code I'm going to drop in my CSS. .WikiaArticle h2 { border-bottom: solid 1px #252525; font-size: 18px; margin-top: 30px; overflow: hidden; padding-bottom: 3px; }

I want to give the rest of the h# lines the same nice looking "border-bottom: solid 1px #252525;" but so far doing experimental edits in chrome on this side and adding said line like below doesn't work.

.WikiaArticle h3 { border-bottom: solid 1px #252525; }

Could someone clue me in to what I'm missing to make this work?
