I was wondering if there is an alternative to using position absolute. I have a logo using this and it does not show in ie6. Ie7 and firefox are fine. I have tried using position fixed and position relative but it will not display correctly. It leaves a very large gap between the logo and the horizontal nav bar.

Did you put the logo into a containing div? I've done that countless times and never had a problem with IE*.

I am a complete newbie with css. Here is the logo code:
<div id="header">
<p class="logo">Text Here</p>

and here is the css:
#header .logo {
margin:0;
padding:0;
position:absolute;
top:0;
left:25px;
width:245px;
height:64px;
text-indent:-9999px;
background:url(../images/logo.jpg) no-repeat;
overflow:hidden;

}

You can take the text-indent part out. That does you no good. In fact, you can even take the p tag out of the equation and have something like this:

<div id="header">
Logo image code here
</div>

And for your CSS:

#header {
     position:  absolute;
     top:  0;
     left:  25px;
     width:  245px;
     height:  64px;
     overflow:  hidden;

I'd suggest that you should code your logo in as the hyperlink to your home page e.g.

<a href="your home page">(your logo}</a>

A lot of users are conditioned to think that the logo links to the home page.

Im not sure that you really need to use positioning at all. You might just be able to use some padding. Do you have a page online so we can see the layout?

I agree with Stephanie, positioning isn't necessary. If you're going to have anything else in the header besides the logo, you should consider floating it left. If that's all that will in there, then the float shouldn't even be needed, just margin and/or padding to push it over.
