Theme development

Hi there. I am by no means a coder... but what I would like to do is write a script that will check if a certain block id (eg: id="block-menu-54") is visible, and if it is, swap an image in my navigation to the active state.

Does anyone know how to do this and what would be the best way to set up my rollovers to correspond with this?

I'm trying to change the number of columns that my theme has, from two to three, when a user logs in and then from three back to two when a user logs out and becomes a guest to the site.

Any suggestions?

Hi
After searching the Handbook for three hours, I give up and ask for a little advice here in the forums.

How can I change which links show over the forum? And style them? And what they link to?

* My discussions.
* Active discussions.
* Post new forum topic.

I'm having a problem with the getfirefox theme. I have a form on my page with buttons for submitting the form and for clearing the form. my submit button is themed but my clear button is not?!

Hi all,

I am having an issue with my blog. http://juxtaflo.com/blog

When theming the blog area I can use the class "class="node node-blog"" and I can control anything. The problem is that there is no way to change either the teaser or the body page seperately. A change to one is a change to both. Really the only change I want to make is removing the border around the entire node in the body page.

Maybe this isn't the best way to go about it: BUT I'm using the BlueMarine Theme as a template to build a fairly stripped out layout that has the coding to place content in the header, footer, .....

Problem is I am getting these lines at the top of the header and top of content and can't find where the code for them is coming from.

Found another post, I think covering the same issue, though it wasn't answered... something about the Nice Menus maybe?
