problem with index.php when attempting asides code

Dear Mr. Obvious,

I have been trying to implement asides on my home page, and, though it appears to work right now, it isn’t quite right.

When I insert the following:
border-left:4px solid #356ac0;
the left colored border appears next to the aside, but it also goes all the way up the page. It ‘borders’ the aside and all the posts I’ve made since then.

When I firebug it, I can see that the ‘entry’ div doesn’t close before the ‘linklog’ class starts. (ie, the more recent post isn’t closing out the div and bleeds over into the aside div)

Here is the page: http://angeloarchive.com
And here is the index.php code: http://brock.pastebin.com/m78007b13

Probably overlooking something obvious.
