Hov­er­At­tribute is a jQuery plu­gin that allows you to make (link-)elements more dynamic by mak­ing an attribute of that ele­ment show up on hov­er­ing. This is fore­most intended for <a> tags resid­ing within full-width ele­ments, such as head­ings or list entries. Amongst sev­eral options, it is pos­si­ble to choose any attribute (href by default, see Usage) of a given tag.
