jQuery - Setting background position from variables
<p>Im getting the X and Y co-ordinates or a selected area, Im then using that to set the position of an image in another DIV.</p>

<p>Vars: </p>

<pre><code>selection.x1 (This will need to be a negative value)
selection.y2
</code></pre>

<p>I need to write using Javascript or jQuery the following:</p>

<pre><code>div.css('background-position', -selection.xl selection.y2);
</code></pre>

<p>But this just give me an error, how can I add two background postion values to the CSS?</p>
