框阴影：隐藏顶部阴影

Question

I've read like 10 questions here and could not apply them to my situation.

I've created the example here

http://jsfiddle.net/Y4uHm/4/

I need to hide the shadow on the top side of the content box. I am not sure if I am doing it right or I should tailor image in some other way. I believe it can be done in some more smart way than using background to create side shadows. Thanks.

To satisfy the rules:

HTML code

<div class="container-wrapper">
   blahblah header is here
 </div>
 <div class="container-wrapper breadcrumbz">
   <div class="pusher"></div> <!-- only for experiment. i know about margins and paddings :) -->
   <div class="content">
      There should be no shadow on top of this block
   </div>
 </div>    

CSS

body {
    background: #4ca8cb;
}
.container-wrapper {
    margin: 0 auto;
    max-width: 500px;
    padding:0 50px;
}

.breadcrumbz {
   background: url('https://dl.dropboxusercontent.com/u/14562883/shadowline.png') no-repeat top center;
}
.pusher {
    height: 14px;
}
.content {
    box-shadow: 0px 0px 3px 1px #555;
    background-color: #e7eaeb;
    height: 200px;
}

Update

I've solved that. The solution is need to be improved but I got the method.

I can move the bottom block "under" using

position:relative

and negative margin

you can use :before pseudoelement

        .content {
            background-color: #e7eaeb;
            height: 200px;
            position: relative;
        }
        .content::before {
            content: "";
            position: absolute;
            width: 100%;
            height: 198px;
            background-color: transparent;
            z-index: -1;
            box-shadow: 0px 0px 3px 1px black;
            top: 2px;
        }
