Align two Adsense blocks above footer

[ChangeFive]

I am trying to align two Google Adsense ads above the footer and on the same line. I have tried several ways to align them and am now using:

<div>
<SPAN STYLE="float:left"> *adsense code*
</span>

<SPAN STYLE="float:right">*adsense code*
</span>
<div style="clear:both">
</div>

This gets me:


I have also tried to float center the right adsense add, but then they are right against each other and touching. What I would like to do is have a little bit of space inbetween both of them, or somehow float them left and right within a specified fix width? I'm sure someone out there knows how to do this better than I do.

Thanks for looking!
