/**
 * Contain floats
 *
 * Make an element expand to contain floated children.
 * Uses pseudo-elements (micro clearfix).
 *
 * 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 the
 *    element.
 * 2. The use of `table` rather than `block` is only necessary if using
 *    `:before` to contain the top-margins of child elements.
