-// Clearfix
-//
-// For modern browsers
-// 1. The space content is one way to avoid an Opera bug when the
-//    contenteditable attribute is included anywhere else in the document.
-//    Otherwise it causes space to appear at the top and bottom of elements
-//    that are clearfixed.
-// 2. The use of `table` rather than `block` is only necessary if using
-//    `:before` to contain the top-margins of child elements.
