Device Specific Javascript, preferably JQuery
<p>I have a pretty Jquery-heavy site in the rollout. However, since it uses fullscreen backgrounds ... which are pretty useless on mobile devices I would love to deactivate the Jquery plugin on mobile devices... </p>

<p>I tried to research this problem but did not came up with a simple solutions... </p>

<p>Media queries won't really do... since there's too much reliance upon Javascript... 
media Queries are CSS-only right (I am more a designer than a programmer.... )</p>
