Don’t let images screw up your baseline grid!

I like to joke about being obsessed with getting everything to line up, always. It might not be a joke…

I’m not sure if this is the right thing to do, but I do it anyway, because it gives me immense pleasure to see the results. I’ve been told I’m just plain wrong for even considering it, but a little while ago I decided I can’t let variable height images screw up my baseline flow. So I got some help from the internet, Dan Neame, and my fantastic co-worker Señor Magnus Holmes, and we came up with this atrocity:

$(window).resize(function() {
	var lineHeight = parseInt($('body').css('line-height'),0);
	$('.baseline').each(function() {
		var closest = ($(this).height() / lineHeight) | 0,
		bottomMargin = (closest*lineHeight) - $(this).height() + lineHeight;
		$(this).css('margin-bottom', bottomMargin);
$('.baseline').load(function() { $(window).resize(); });

Now all you have to do is add the class “baseline” to any element you need to respect the baseline flow, and problem solved!

Now, I am pretty sure it’d be a very bad idea to do this on hundreds of elements at once, but if you’re having a few problems getting things to line up, this is a decent solution. In fact, I use it on the lead text on this very post, to prevent the odd line-height to mess up my groove. I’m sure there are smoother ways to do this, and I’d love to hear what your suggestions on how to improve this! Tweet!
