CSS Help Needed :) Thanks!

Glad it worked for you, was it just the margins or both the margins and the fixed?

For your next inquiry, I do not see what decorations you are talking about on the headers. I do know a neat trick to do with CSS to have the graphics on your h1, h2 etc tags like you describe. It involves position:relative.

You would have the dollars flowing graphic img in your html right before your h1, h2 tags. Say you have your h2 tags centered on the page also. In the CSS for the img, it to would need to be centered, then use the position:relative

.dollar img {
position: relative;
top: 10px;

What this will do is there will be a space above your h2 tag for the graphic, but it will then be offset from the top 10 px, or in other words move down 10 px on top of anything there already. You'll have to play around with the value to get it just right, but it should do the effect that you are looking for.

UPDATED : see post after this one for simple stuff.

It is real difficult to explain exactly what he is doing, but I get it.
His HTML and CSS for that header is below, this what is making it all happen.

In the CSS decor -1 is the crown, he is using float and z-index to put it behind his blue background for that header. the negative value margin moves it outside his content area. z-index lets you "stack" in any order you want, the higher the value, the more up front it is.

decor-2 is that little triangle that makes the header appear to wrap around the content area.

As you can see, who ever built this knew a lot about creating effects with CSS, it is a lot of work and I'm sure a lot of testing went on for whom ever wrote the code. The concept is simple, getting the right rules and the values for them in a lot of cases is all trial and error for creating something for the first time.

html
<div class="apost">

<div class="decor-1"></div>
<h2 id="post-1630"><a href="http://zacjohnson.com/how-to-leverage-ppv-traffic/"
rel="bookmark" title="Permanent Link to How To Leverage PPV Traffic">How To Leverage PPV Traffic</a></h2>

<div class="decor-2"></div>

css

#content .apost {
width:100%;
margin:0 0 30px;
clear:both;
}
#content .apost .decor-1 {
float:left;
display:inline;
margin:-37px 0 0 -56px;
position:relative;
z-index:12;
width:85px;
height:37px;
overflow:hidden;
background:url(images/crown-left.alpha.png) no-repeat;
}
#content .decor-2 {
float:left;
display:inline;
margin:0 0 0 -39px;
position:relative;
width:19px;
height:18px;
overflow:hidden;
background:url(images/tag-left-blue.jpg) no-repeat;
}

Where you put it in the stylesheet is going to be again a testing thing, it has all to do with "FLOW", how the CSS is ordered and what is going to take precedence.
