How to adjust width of modules?

Hi,

Can anyone tell me how to adjust width of the modules that are in the same line.

Let's say I have one module in a position top1 and another in a position top2. At the moment both modules share 50% of the whole width when enabled, but I need to assign 70% to module top1 and 30% to module top2.

Any idea where to set module width to a certain percentage?

Thank you

Hi
I think you will need override.css and !important rule. Can you give me url to your site?

Thanks, I've done it myself. Just set width for modules in layouts/blocks/topsl.php
