Theme development

Hi,

I just started drupal a week ago and I can't seem to find a decent guide on theme hacking. Is there any nice and straight forward tutorial out there that explains everything nicely?

Thanks,
Ben

I really like drupal's own site theme. However, I've been looking around, and can't find it. Does anyone know if this is public? Thanks.

FYI: I'm relatively unfamiliar with Drupal, I've come from the Joomla environment. And I'm using Terminal and SVN to manage this project on our server.

Goal: In the Drupal admin>build>themes page there should appear a list of the themes coming from the literal themes dir.

Problem: However, they are not appearing and I do not know why.

1. Using the Aberdeen Liquid theme, I've setup several meun items as primary links. Clicking on the Home and the Contact menu tabs only appear as a outline where as the other menu items are solid tabs. How do I change the theme so all menus are solid tabs? Just noticed, if I click on a different menu all tabs are solid. Only happens when clicking on the meun item itself.

2. There is a 'Back to top' link on all pages. How do I remove it from pages where it is not required like Home page or short articles, but keep it on other pages which require it?

Is there a way to find out what variables (not sure if that is the right word) are available to use in the theme from any module.

Hi,

I need to know which theme is best for customization. Right now i am customizing the theme bluemarine , but i dont know how to customize the sidebar . Because in page.tpl.php file in blumarine theme they just call the variable $sidebar , so we cannot rearrange or cannot insert any info in between the menus.

can any body please guide me for that ?

Thanks in advance
