CSS method for moving metadata in Sela?

Hello,
I am playing around with Sela’s CSS and I’ve more or less gotten things how I like them. There is one big issue, though. For stylistic reasons, I moved the post titles and post body over toward the left margin. Here is the code:

.post-thumbnail + .entry-header {
	margin-left: 3em;
	margin-right: 6.5em;
}

div.entry-body {
	margin-left: -4em;
	margin-right: 6.5em;
}

Now, the issue is that the body of the post overlaps with the metadata. Is there a CSS trick for a) moving the metadata farther left, b) moving the metadata to under the post title, or c) moving the metadata to the bottom of the post? I am not terribly picky about where it goes because all three options have the potential to look nice.

Thanks!
