id=footer location & multiquote issue

[Lpspider]

Okay, long story short -

I created a custom footer design I love. I just realized multi-quote isn't working. Turns out when I revert the footer it works, therefore the footer template is causing it. After trial and error I narrowed it down to this:

    <div id="footer" class="floatcontainer footer">

then managed to narrow it down to just the id="footer". When I remove the above code, it breaks multiquote. I need to remove or alter it to keep the custom design I came up with.

Some property of footer affects multiquote. My question is twofold. Firstly, where can I locate and edit the CSS id footer? Stylevars doesn't look promising, or additional.css. Secondly, does anyone know why or how this could be affecting multiquote functionality?
