Center column as a homepage

[an.internet]

Hello!

 

I want to change a 3 columns theme into a 2 columns, but I want the center column to be 960 px width and 400 px height. I have removed the right column, but it doesn't give me the opportunity to adjust the center column. Can anyone help me?

 

Thank you!

 

 

 

P.S. I am using prestashop 1.5
