I want id="bottomContent" to stick.

I'm taking this approach...

Code:
html, body{height: 100%;}

#wrapper{
	min-height: 100%;
	margin-top: -432px;
	}

* html #wrapper {/* ie6 and under only*/
    height:100%;
}

header {
	height: 100px;
	margin-bottom: 10px;
	border-top: 432px solid red;
}

#bottomContent{
	position: relative;
	float: left;
	height: 432px;
}
It still seems to be a few pixels off. I Inspected Element of my bottom content and it says 432? Is there a better way to double check this?
