// 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.
