1 // Clearfix

     2 //

     3 // For modern browsers

     4 // 1. The space content is one way to avoid an Opera bug when the

     5 //    contenteditable attribute is included anywhere else in the document.

     6 //    Otherwise it causes space to appear at the top and bottom of elements

     7 //    that are clearfixed.

     8 // 2. The use of `table` rather than `block` is only necessary if using

     9 //    `:before` to contain the top-margins of child elements.
