[DHTML] Old Internet Explorer, Different Stylesheet

[Riq]

1) CODE TITLE: Old Internet Explorer, Different Stylesheet

2) AUTHOR NAME/NOTES: Rik Dekker

3) DESCRIPTION: Internet Explorer 6 and below dont support the position: fixed; attribute in CSS. Therefore if you use the attribute it will really mess up your design.

So this script detects if you use Internet Explorer 6 or below and then attatches a different stylesheet.

In any other case (Opera, Safari etc.) it just loads the normal stylesheet.

Browser detection is bad (and, done like this, inaccurate). If you need to do this, use conditional comments:
<!-- [if IE < 7]>
<link type="text/css" rel="stylesheet" src="ie.css">
<![endif]-->
<!--[if !IE]>-->
<link type="text/css" rel="stylesheet" src="other.css">
<!--<![endif]-->

Your text file doesn't make clear whether you know how to emulate 'position: fixed' in IE<7.
Using the underscore hack, you could have something like the following for a fixed position on top in all browsers:
<div style="position:fixed;left:0;width:100%;height:35px;background:white;top:0px; padding:2px;_position:absolute;_top:expression(eval(document.compatMode && document.compatMode=='CSS1Compat') ? documentElement.scrollTop+screen.height*0 : document.body.scrollTop+screen.height*0)"></div>

But we don't like hacking, so we could use the above coding in conditional statements (without the underscores), as suggested by Twey.

Important: just to make sure that there is no 'trembling' of the fixed div in IE when you scroll down, the body should be styled as:
body{background:url(foo) fixed;}
