I'm working on a contributed theme that makes use of the following 
layout. I've found this layout to be the most *robust*. And seeing as 
how I have deadlines, am under payed, and not doing the conference 
circuits as a CSS guru yet, I'm not really too concerned about the 3 
non-semantic divs. I'm concered about having a well ordered, table free 
layout that has a footer, can expand and contract with drupal's 
oddities, works on the  rest of the world's web browsers, and has 
min-max width support for IE as well as firefox.

What really attracts me about this layout (which Kieran's like may not 
do as gracefully, but I need to test that...) is that using PHP to 
calculate the sidebars, I can remove, and add columns on both or all 
sides cleanly by setting seperate classes for the #columns div.

Generally, I've found that most of the overriding of drupal.css can be 
done by zeroing in more specifically on the elements. Example:

.block .content .item-list li,
.block .content .menu li  {
    padding:0;
    margin:0;
    list-style-type:none;
    list-style-image:none;
}

removes the drupal.css formatting for menus and item lists in blocks in 
a box_grey-like theme. drupal.css specifies ".item-list li", so you can 
override it by getting more specific: e.g. " #content .sidebar .block 
.item-list li" if you were crazy. Similarly, the .clear (which I find 
necessary given the floats for logo, and navigation that are often in 
the header) could theoretically be overriden by specifying #header 
br.clear {clear:none;}

When in doubt, use the ID -- as they have precedence over classes.

Best,
