Ajustar Height de los divs

[[NiRVaNa]]

A ver te dejo un codigo CSS que yo uso y me funciona sin problemas, alo mejor te sirve:

Código HTML:

/* Boxes */
#top {
	margin: 0px 0px 0px 0px;
	padding: 10px;
	border: 0px;
	background: #fff;
	height: 165px; /* ie5win fudge begins */
	voice-family: "\"}\"";
	voice-family:inherit;
	height: 145px;
	width: 928px;
	text-align: center;
}

html>body #top {
	height: 145px; /* ie5win fudge ends */
}

#left {
	position: absolute;
	top: 165px;
	left: 0px;
	margin: 0px;
	padding: 10px;
	border: 0px;
	background: transparent;
	width: 230px; /* ie5win fudge begins */
	voice-family: "\"}\"";
	voice-family:inherit;
	width: 210px;
}
html>body #left {
	width: 210px; /* ie5win fudge ends */
}
#right {
	position: absolute;
	top: 165px;
	left: 230px; /* Opera5.02 will show a space at right when there is no scroll bar */
	margin: 0px;
	padding: 10px;
	border: 0px;
	background: transparent;
	width: auto;
	width: 698px;
	voice-family: "\"}\"";
	voice-family:inherit;
}

/* End boxes */

Lo unico que tienes que hacer es acomodarlo a tus tamaños...

Enjoy. Salu2!
