How do you use jQuery( elementArray )?
<p>I set these up at the beginning of the script:</p>

<pre><code>var grid = $('#grid');
var lines = $('#lines');
var background = $('#background');
</code></pre>

<p>Elsewhere in the script, I need to change the CSS for all 3 elements at the same time. Rather than doing this:</p>

<pre><code>grid.css({...
lines.css({...
background.css({...
</code></pre>

<p>I want to do something like one of these:</p>

<pre><code>$(grid, lines, background).css({...
$([grid, lines, background]).css({...
</code></pre>

<p>However, the only thing that seems to work is by referencing the IDs directly, like this:</p>

<pre><code>$('#grid, #lines, #background').css({
</code></pre>

<p>I'd prefer to use references to the elements instead of the IDs directly, as they may change dynamically. Is this possible?</p>
