Title: Small defect inside ccs file

Here is the small defect http://twitter.github.com/bootstrap/scaffolding.html when you hover any element inside live grid example - hovers all elements inside show-grid line. I think the idea is to hover just one element.
Also you can check this request https://github.com/twitter/bootstrap/pull/6706, because of mistake on the same page
