Theme development

I've studied over 20 Drupal themes trying to find one for my site (migrating from Wordpress to Drupal), and every time I see a pure CSS theme (i.e. not using tables for layout) I always check the bug tracker and find that people have issues with sidebars nor being rendered correctly in some browsers. My old no-tables Wordpress theme had the same issues. I am wondering if this is really worth the trouble. What are the practical benefits of using pure CSS theme instead of putting a 2-cell table for layout and styling the rest with CSS?

hi everyone,
i have a somewhat complicated situation.

hi everyone,
does anyone know how to style the submenus separately from the main menus?
for example, let's say i want my main menus to have white text on black background, but any submenus (fly-out menus) to be red text on green background.

thanks!!!

Currently I have the problem, that user, which are already logged in, get the no-access-page, when they try to log in again.

Is there a way or a setting to send them to their account page instead?

Thanks

Hey guys im trying to split the front page up so that it shows the content in the specific catagories. Right now i can get them to show almost, but i need to also be showing the actual term name or catagory name above the specific news... i know it can be done but the question is how... I also know it can be done with views but again how

Thanks

hi everyone,
how would i be able to tell if a person who is viewing a given page (or node) is logged in to drupal? basically i want a page to act differently depending on whether or not the user is logged in, like:

if user_logged_in {
// execute code for logged in users
}
else {
// execute code for non-authenticated users
}

i couldn't find anything in the drupal api to do this with. any tips?
