title: add close button to appear in div elements without modifying mark-up
body: <p>I'm wondering if it's possible to add, and then of course style, my <code>close</code> button that would simply close the current element <em>(or hide current div)</em> on click. I want to do this without manually going into the mark-up and writing the html for a close div. I'm wondering if a purely jQuery or JavaScript solution is possible.</p>
