It is extremely lightweight and very smart in * that it detects the edges of the browser window and will make sure * the tooltip stays within the current window size. As a result the * tooltip will adjust itself to be displayed above, below, to the left * or to the right depending on what is necessary to stay within the * browser window. It is completely customizable as well via CSS. * * This TipTip jQuery plug-in is dual licensed under the MIT and GPL licenses: * http://www.opensource.org/licenses/mit-license.php * http://www.gnu.org/licenses/gpl.html */
