Theme development

I'm currently using a modified version of the bluemarine theme.

I noticed while testing other browsers that in firefox, opera (and opretty much every except IE) theres a 1px tall line under the header/above the main content area. I've tried everything to get rid of it, but cant actually seem to find whats making it. Could anyone help me out possibly?

my site is here : http://www.heartlessdesign.co.uk/loading/

HI !
Is there a possibility to customise how the node/add page is displayed ? If so, how can I do that please ?

Thank you.

For the moment my website http://www.tolkienlibrary.com/ is completely static; and i'm seeking to make it more dynamic.
I wish to be able to convert the current site towards a drupal site. Yet being able to write html, css, ... i just don't seem to be able to build a theme that works for me. First of all i'm a bit confused about the menu system. I can easely recreate the menu and submenu, and 2nd level submenus: but how do i need to link these? The 2nd level menu does not even appear at all.

Hi,

andreas01 is a great theme. Is anybody porting it to version 5.x?

Best regards

odie.

This is probably very basic, and I'm new to Drupal, so I'd appreciate any help:

I am working with Bluemarine and added a new image inside a new block above the header. It looks great on the frontpage and most admin pages, but the new image disappears when using any of the modules (search, blog, etc.) The block where the image should be is still visible, but the image is gone.

Can someone point me to info on how to upgrade a 4.7 theme to 5.0? I have a custom theme originally developed for 4.7 (based on the Fundamental theme) and some 5.0 modules (htmlarea, TinyMCE, Javascript Countdown Timer) don't work. Is this a theme issue? Thanks.
