Theme development

I have been working with Drupal for about a week now - obviously not very long. I'm working with the FriendsElectric theme and am making some modifications to it because of a template that I'm using for my client. I would like to center the top links that appear in the header. I can't seem to get the CSS working to accomplish this. I'm hoping that someone else has worked with this theme and has done this same thing.

THANKS!

I've found a great problem. The textareas in 4.7 are replaced with javascript for a fancy resizable textarea but, trying to modify them via css won't work for me...

The problem I have may be a bigger problem.
the "main" div (for content) is a normal block box
but on the right I've got a floating box (right side pane).

I had an idea! I was wondering if it would be possible to automatically change themes based on the time of day (i.e. day and night)? I don't really know where to start on that, but it sounds simple enough. Maybe I'm barking up a huge tree, but if anyone could give me some idea, that would be great!

I have a couple of questions regarding the ecommerce module:

1) I can easily add products to my shopping cart but when I try to "checkout" I get a blank page as if there
is something wrong with the module. Does anyone have any idea why this happens?

2) Can I set up a payment method by credit card? would that be tha ccard.module? or is that used for something
else?

Can anyone give me any suggestions considering I'm building an ecommerce whereby products would only be order by
a certain minimum amount

I have a variable ($tracking) defined in page.tpl.php . I'm trying to access this variable with code that's embedded in the body of a regular page node (input format set to PHP).

How do I get individual nodes to have access to variables defined in the template file?

I had someone working on theme development and just messing around in general, and they deleted the primary links menu from the site.

Now it is still showing up as Edit Primary Links, but I can't figure out how those menu items are created since they are referred to be themes in general, and have their own variable. I tried creating a new menu item called Primary Links but this didn't replace it.

Is this a bug in the menu system or is there a simple way to fix it from within Drupal ?
