Example Respondo Bootstrap modal shortcode

respondo-bootstrap-modal-shortcode.php

<?php
/* Bootstrap Docs:
 * http://getbootstrap.com/javascript/#modals
 * Lots of options could be added as attributes in the shortcode. The attached code is just the pieces I needed at the time.
 * This is the simple shortcode:
 * [sls-modal id="modal-1" header_text="HEADER TITLE HERE"]
 * CONTENT HERE
 * [/sls-modal]
 * One thing that should be changed, is to allow for other respondo shortcode to be used within the content part. 
 * I hadn't shorted that out yet.
