I need to open the squeezebox in the middle of the screen. I'm using joomla and this is the line of code that is giving me problems:
<a class="modal" href="//www.youtube.com/embed/tGKATMITCnA?rel=0&wmode=opaque&autoplay=1&controls=0" rel="{handler: 'iframe', size: {x: 480, y: 270}, onClose: function() {}}">video</a>
The popup opens at the top of the screen, rather than in the middle as expected.
