Element Align Problem - Negative margins, images etc - html

Question

I'm trying to make a header that goes outside the borders of my sidebar and has a shadow image that makes it look like it is a book-mark.
Something similar to this: http://inelmo.com/images/img2.png
Right now I tried my best, but it is not looking correct. here is my code for sidebar and header That I think should work to make this effect, but it isn't.
HTML
<!-- Sidebar -->
<aside id="sidebar">
<!-- header div -->
<div id="sideProfile">
<!-- Span with image background -->
<span id="sideHshadow"></span>
</div>
</aside>
CSS
#sidebar {
padding: 15px;
width: 400px;
}
/*Span with shadow image to make it look like a bookmark */
#SideHshadow {
height: 6px;
width: 12px;
margin: 0 0 -6px 0;
float: right;
background: url("../images/sidebar_header_shadow.png") no-repeat;
}
#sideProfile {
background:#333333;
border-bottom: 1px solid #2d2d2d;
height: 50px;
width: 400px;
margin: 0 -12px 0 0;
box-shadow: 0 1px 2px #77bee6;
-moz-box-shadow: 0 1px 2px #77bee6;
-webkit-box-shadow: 0 1px 2px #77bee6;
-webkit-border-radius: 7px 7px 0 7px;
-khtml-border-radius: 7px 7px 0 7px;
-moz-border-radius: 7px 7px 0 7px;
border-radius: 7px 7px 0 7px;
}
Anyone knows how to make it look like in example? Thnx

Here's a pure CSS version: http://jsfiddle.net/bcZKh/2/
Code below:
<div id="list">
<div class="item selected">Nationwide Coverage Area</div>
<div class="shadow"></div>
</div>
body {margin:40px}
#list {width:200px;border-radius:8px;min-height:200px;background:#E6E5E0;padding:20px 0;position:relative}
.item {color:#fff;font-size:0.8em;line-height:24px;font-family:sans-serif;text-indent:24px;margin-right:-12px;margin-left:-12px;position:relative;z-index:1}
.item.selected {background:#C74312;border-radius:4px;border-bottom-left-radius:0}
.shadow {border-color:transparent #733411 transparent transparent;border-width:12px;border-style:solid;height:0;width:0;position:absolute;top:32px;left:-24px;z-index:0}
