CSS: Titles aligning on baseline

Hi there,

Could anyone tell me how I might align my post titles on the baseline (so bottom up). I can’t seem to figure it out, here’s what I have currently tried:

<div class="post_title">
	<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2>
</div>

And the css:

.post_title {
	margin: 0px;
	height: 60px;
	vertical-align: baseline;
}
.post_title h2 a {
	vertical-align: baseline;
}

Any help would be greatly appreciated.

Thanks

Chris
