<h2 id="modals-related-target">Varying modal content based on trigger button</h2>
<p>Have a bunch of buttons that all trigger the same modal, just with slightly different contents? Use <code>event.relatedTarget</code> and <a href="https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_data_attributes">HTML <code>data-*</code> attributes</a> (possibly <a href="http://api.jquery.com/data/">via jQuery</a>) to vary the contents of the modal depending on which button was clicked. See the Modal Events docs for details on <code>relatedTarget</code>,</p>
