Align Multiple Posts in One Line

Hi,
Im relatively new to wordpress theme creation though Im loving it every bit.

I am trying to convert this theme:
http://www.templatemo.com/templates/templatemo_245_redox/templates.html

to wordpress.
I have managed to get the content and the loop working. Now the problem is that the posts are appearing vertically compared to the 3 column layout shown in the template.

I tried to modify the CSS but its not helping.

Please advise
