Yea - CSS 2.1 Complaint but not XHTML

I'll get to this when I have time.
Unless someone would like to write a patch, I can commit it.
Thanks

The theme passes CSS 2.1, CSS 3, fixed, US 508, Wave, WCAG A, and XHTML 1.0 Strict tests on http://d-theme.com/dreamy. WCAG WAI tests show just one change is needed to reach an AAA rating. There is an empty link that breaks WAI AA rules.
<a class="feed-button" href="/rss.xml"></a>

There are two h1s, not a good idea. Perhaps the following line could change.
<div id="header"><h1 class='site-name'><a href="/" title="Home">D theme for da Web site</a></h1></div>

To:
<div id="header"><a href="/" title="Home" class="site-name">D theme for da Web site</a></div>

or:
<div id="header site-name"><a href="/" title="Home">D theme for da Web site</a></div>

While you are working on the patch, consider this change. The menu bar background did not run beyond the first line of the menu. When I shrink down the screen at http://d-theme.com/dreamy, the menu div does not expand vertically to cover the second and third line of the menu. I made a variety of changes and one worked.

In style.css, remove height from #menu. Then add the following dummy division to put invisible content after the menu so the menu div will extend to the end of the menu.
ul#navlist:after
    {
    content: ".";
    display: block;
    height: 0;
    visibility: hidden;
    clear: both;
    }

There are hundreds of thousands of pages online where people ask for help with this problem and are told it is IE only, despite many of the problem reporters using Firefox 2 or 3. I get the problem in the almost new Firefox 3.0.5. Most of the Drupal themes with horizontal menus have the same menu breakup. A nicely fixed working example would be good. A nicely fixed working example with an official recommended release would be best.

Grab the enclosed image and add it to the theme. Change wrapper to:
#wrapper {
margin:0 auto;
width: 900px;
background: #f3f3f3 url(images/bg-header-right.jpg) repeat-x scroll 0 0;
font-size:1.20em;
}

See the effect at http://d-theme.com/dreamy. The theme is one step closer to being width independent. bg-header-right.jpg fills the top space without breaks. #f3f3f3 provides a continuous grey instead of the cheap substitute provided in the page background image.

The only bit left is the grass at the bottom. You could then make the width an administration setting.

The grass is solved easily. Change the image in #footer from no-repeat to repeat-x.

Cool. I'll look into these on the weekend.
