Yep. 70% + 30% > 100%... at least sometimes, or to be more price: every 
10px times ;-) This is because every 10px the reminder is 0.5px, thus 
both 70% and 30% get rounded up, which brings the total width to 100% + 1px.

You have:

#sidebar {
	float: right;
	width: 30%;

Change 30% to 29.5% and the side boxes drop no more.

<tip type="CSS" author="kasimir k">

If you want to avoid falling floats and/or horizontal scroll bars, you 
should avoid widths totaling to 100% - e.g. with widths 70% and 30% and 
1005px available space you get
70% = 703.5px => 704px
30% = 301.5px => 302px

Using 70% and 29.5% will save you from hefty head scratching.
