Theme development

I opened xtemplate and see that the colors are listed as:
______________________________________________
body {
margin: 0;
padding: 0;
color: #000;
background-color: #fff;
font-family: verdana, arial, helvetica, sans-serif;
font-size: 76%;
}
tr.dark {
background-color: #ddd;
}
tr.light {
background-color: #eee;
}
_____________________________________________________________

Can I give a different look to two blocks (box in a sidebar) in a same template on a same page ?

I don't know how to configure drupal for use a different block (piece of HTML on xtemplate file) for each block.

I'm using a 4.3.4 drupal.

Sorry, for me english !

Hello,

I am new to Drupal, I'm a convert from wordpress and I don't know all that much about php. I want to change my drupal installation from the default themes to a new downloaded one, namely the Trip theme which you can download from this site.

But I keep getting this error:

Fatal error: Class theme_trip: Cannot inherit from undefined class basetheme in /home/nik/public_html/mylagoon/themes/trip/trip/trip.theme on line 1

Can someone please explain what this means?

Hey,
I'm changing some values in the Marvin theme to fit me better, but I don't know where to change the right column (with the boxes) size. I want to make it larger in a "kerneltrap style".
Sorry for the newbie question, I'm starting to learn drupal...
Tnx in advance

Does anyone know how to make the title of a node link to that node, for example on drupal.org "Drupal 4.4.0 release candidate" the title is a link to the node. I had help from another user with this issue, but I couldn't get it to work properly.

When a blogs title was clicked, it would link to /weblink/goto/### when it should link to /node/view/###. This would bring up a 404 error. But if a weblinks title was clicked it worked fine.

I am new to css but I have been trying to use css to insert an image into a class.

.buttons {
border: 1px solid #999999;
background-image: url(/themes/xtemplate/iis/twor_graphics/grad1.gif);
background-repeat: repeat-x;
background-position: left top;

For some reason it doesn't work. I think the the url address is wrong but i copied and pasted it from where I source my banner/logo and then changed the name of the image file:

img src="themes/xtemplate/iis/twor_graphics/twor_logo1.jpg" alt="Logo"
