[CSS] Move articles on home page

Hi all. I have a theme that have options to display 4 custom categories on the home page. But the categories articles are one under the other.
The articles are one by one only if those are from the same category, but if i select to show only 1 article from the category, the articles will be one under the other.

I tried a lot of things but i wasn't able to place two articles from different categories one by one. I will show you the example, website and the CSS source. Thanks a lot.

You have to give a width to that div and float left.

This should work dude.

Thanks a lot, but i have a little issue, the above code almost done the job, but not entirely.
