converting jquery to pure javascript
<p>I have a function that creates an image with the canvas object. The last line of the function says this:</p>

<pre><code>$('body').css({ 'background-image': "url(" + Canvas.toDataURL("image/png") + ")" });
</code></pre>

<p>I'm looking to convert this line into pure javascript to remove the jQuery dependency. Any suggestions?</p>

<p>Thanks.</p>
