Hi deathshadow yeah I am trying to use it in the way Ralph explained. I am changing
to clearfix according to a tutorial I am following (found when googling).
This is legacy html on a wordpress theme I'm customizing, so my initial question was because I was questioning the reason for
being there in the first place. I couldn't actually see any error or change when I deleted the line so I was just wondering in what instances it would create problems without it. Anyway I think it may have just been that the wordpress theme html was badly written and now my new clean code has got rid of that issue or needing to clear content. Hope I (: am making sense!
