Hie,
Thank you all who answer questions here.
I've got a minor problem, but probably somebody knows how to correct it.
My main page is layout-three-column, others, like archive templates are layout-two-column, but I would like my articles to be shown at the whole page. I need just one column for my articles, so I cannot do it. It seems I tried everything, but still article is 520px wide, not 890 as it should be.
Any solution for that???
Thanks in advance

Hi Russo,

I don't know what's your CSS knowledge level is, but have a look at this page, it's really helpful and it explains everything in lame terms:

Understanding the new themes

It'll help to explain, allowing you to understand MT's complex CSS layout system. In future, it'll help, to supply a link back to your site, so other's can help you solve your problems.

Good luck.

I'm using Arvind's Style Generator to achieve the three column look but I'd also like the blog to fill the entire page... Any ideas on how to do this?

Update: I figured it out.
