Css Float Position

[luis12]

I have a section on my homepage which displays an excerpt of the latest posts, and I've create some css for the first 2 post for them to be side by side, but I can't get the second article to float next to the first article. Even if I enter float:right on the second title, it floats to the right , but under the first one. You can see exactly what I mean if you visit my site www.ehowtodrywall.com. How do I get the second title to float to the right of the first title in the latest article section ...Thank You
