<!--
This is an example implementation of a modal.
The boilerplate html has to be structured like this:
<div class="modal-background closed">
<div class="modal">
<div class="modal-close"></div>
<div class="modal-content">
</div>
</div>
</div>
Then you can create a new modal object like this:
var modal = new Modal({selector: '.modal-background', ajaxUrl: '/examples/ajax.html'});
and open it with modal.open() and close it with modal.close()
