CMS cms width adjustment

[محروم.كوم]

Greetings all .look at my home page http://supremacysounds.com/home.php and compare with this http://www.vbulletin.com/forum/content.php

Look at "whats new " how do i make my news column to be the same style as the one on vbulletin.com .also look at "recent comments" and "recent blog posts" how can i make my advertisements be the same size ie width and height like the vbulletin.com "recent blog posts" ? coz my adverts look very squeezed. thanks in advance __DEFINE_LIKE_SHARE__
