Change a wordpress theme from 2 columns to 3 columns?

I am using a silver light theme for my wordpress blog and I like it. You can find it here: http://themes.wordpress.net/columns/2-columns/4366/silver-light-01/

Now how can I make this theme from 2 columns to 3 columns? I know I need to change the css files, just don't know what needs to be changed.

Thanks

 

Anybody here?

 

you should contact the people who are friendly to the wp codes..!!

 

in order to change a WordPress theme from a 2 column to a 3 column you need to have a solid understanding of XHTML, CSS, and at least some understanding of PHP. If you don't have that knowledge, don't even attempt to do it on your own. I would suggest searching for a 3 column theme similar to the one you have or hire a WordPress consultant to alter your existing theme. If you are looking for someone good to do this work be prepared to pay handsomely for this expertise.

 

I'll make the changes for $10, check my Itrader to see feedback from people I worked with. I'll get it done in a few minutes.
