safari background color on body tag bug?

In the latest Safari (Version 5.0.3 (6533.19.4)) background-color css does not affect how the browser renders the color of the background.

I've seen this on a number of sites include the following. (note: remember to use safari)开发者_如何学运维

What's going on here?

It's a bug in safari. For example:

body {
    background-color:black;
}

This won't work in safari because it's on the body tag.

Have you tried short hand? background: red;

I'm not a Safari user. Safari is pretty good when it comes to rendering CSS and complying to web standards and new technologies. Perhaps it's just a glitch, somewhere in Safari's code. I'd be interested to know where / how.

Update: jQuery website is rendered EXACTLY as in Firefox, with background colour showing.

Here on Win7 with Safari 5.0.5 I experience no problem.

Try it on the html tag.

This seems to still be a bug in Safari 5.1. Seen this on many pages. When first entering a page the bug is obviously shown, but rendering adjusts as soon as you do something that triggers a redraw (zooming, scrolling, ...). Very annoying.

It seems to effect Chrome as well, but if you tag to HTML all is well.

html {
    background: #000;
}
