Theme development

hi,
i have several categories, which i put on the navigation-tabs.
when i click on cat. A, there should be a navigation-menu,
which shows only, events of that category.
(an article of my category is also an event).

how can i accomplish that - is it possible somehow ?

hi everybody,

i want to style my frontpage.
my ideas are to have a 3 columns layout,
which is mainly based on DIVs.
you can imagine it as a grid, wihtin the content
should be displayed.

|-----col a -----| ......col b......|
| ----col c --------------------|

col a: has _3_ articles of category A,
col b: has the latest upcoming events,
col c: has all available articles.

what i do not understand is, how to do this.

the grid is ready, but i also do not know, how
to insert the desired code functions.

Are there any Themes for Drupal 4.6 which have a 4 column layout like the Channel Nine theme (which only works on 4.7 BTW). Thanks in advance.

Sorry for the dumb question, but how do I change the font size for the main body copy in a Democratica theme? Is it in basics.css and what part do I change? Thanks in advance! :-)

There is a horizontal line [hr] beneath the menu in the #sidebar_left division of the bluemarine theme. I would like to delete this line in the template. Where in the code is this line printed/echoed?

I am looking for a theme that would look similar if not the same like my site: http://www.tecito.com What is the best theme to hack, customize? I like Mollio and spreadfirefox for my site's theme. Can anyone else suggest a good theme or an easy one to hack?

Thanks in advance.
