Theme development

I want to use the vbulletin forum on a drupal base. There are 2 way's to do this.

1. you install vbdrupal en install vbulletin:
But this is a alterd version of drupal and i need a module that is not compatible with this version.

2. you instal drupal with drupalvb.module and install vbulletin:
This looks like the way i want to do it. But i cant find a way to intergrate vbulletin as a page. Now it just pop's up in a new window.
I want it in the theme, not i a new window.

HI All,

Hopefully this means a significant simplification for theme developers.

I facing a problem that my theme cannot work propertly; the right side bar sometime was shifted to the downward. I tried to modify the style.css, it seems it cannot change. Where I can learn more about the style.css? And Only style.css can modify the theme layout (e.g. page width, sidebar width, block width...).

Thanks

I have managed to port a theme into drupal following the tutorial over at dudertown.com. However, my primary links are appearing vertically, and I want them to appear horizontally like the tabs on this site. They are appearing on the left like I want and the tabs look just fine. The tabs are just appearing one below the other. If this has been addressed somewhere else, please direct me to it because I have been all around looking for a solution. I'm assuming it's easy since I've seen people asking how to replace the vertical delimiter, i.e.

Drupal 4.6.10 and Drupal 4.7.4 now protect forms by default against cross site request forgeries.

Be sure to read about possible consequences for your 4.6 or 4.7 themes.
