Theme development

Hi. I am trying to make my own version of the Marvin theme by writing a style.css. One thing that troubles me is how I make a nice block around my code, just like here at drupal.org:

This is how I want the code to look like.
Line 2

I have looked on the html of drupal.org - and here there is a codeblock-tag which I haven't on my site. Is this acchieved by using a module?

How can I do this most easily?

Is there a list of the classes and IDs that I would need to redefine if creating a theme for Drupal?

I have recently worked on a couple and found that I was clashing with a couple (eg. I've always used the ID 'content' to specify a general area for content, but that clashes with the class 'content' in Drupal).

So I'm looking for a list including the big ones as well as smaller classes (eg. which classes and IDs need redefining to change the look of page numbers?).

Thanks.

Hello,

I'm in need of a very capable designer / programmer to integrate several templates into drupal for us. We have two that need integration currently and many more on the way.

If you're interested, let me know.

Thanks

Hi,

I want to create a static html page with an html form that calls up a php page that does a mysql lookup and returns the results. Both pages should only be accessible to authenticated users. The first static page is no problem to create, but how can I pass the form contents to a php page and still only stay viewable for authenticated users?

Thanks.
