/**
 * TODO: correct inheritance
 *
 * This property describes decorations that are added to the text of
 * an element using the element's color. When specified on an inline
 * element, it affects all the  boxes generated by that element; for
 * all  other  elements,  the   decorations  are  propagated  to  an
 * anonymous inline  box that wraps all the  in-flow inline children
 * of the element, and to any block-level in-flow descendants. It is
 * not,  however,  further  propagated  to floating  and  absolutely
 * positioned descendants, nor to the contents of 'inline-table' and
 * 'inline-block' descendants.
