Skewing divs via CSS - css

Question

Attached is a brief mockup of what I need to create. The div not only needs to skew on the bottom, but the next row will need to skew to the top.
Is there a clean way this can be done using CSS? I've tried some CSS solutions ( e.g http://jsfiddle.net/mXLgF/ ) but can not get this effect.
My current HTML / CSS is at this stage:
<div class="skew_bottom_right">
<div style="height: 300px; background: url('http://placehold.it/850x350');">
</div>
</div>
.skew_bottom_right div:after {
content: '';
position: absolute;
left: 0;
bottom: -60px;
width: 100%;
height: 115px;
background: white;
-webkit-transform: skewY(8.5deg);
-moz-transform: skewY(8.5deg);
-ms-transform: skewY(8.5deg);
-o-transform: skewY(8.5deg);
transform: skewY(8.5deg);
-webkit-backface-visibility: hidden;
z-index: 5;
}
Each of those containers will eventually made into a slide, so ideally they should be div's with background images or containing divs having a background image.

Your code is pretty good.
Just needed some minor adjustments...
.container{
overflow:hidden;
}
.parallelogram {
width: 600px;
height: 100px;
margin: 30px 0;
transform: skewY(5deg);
background: gray;
overflow:hidden;
position:relative;
}
.parallelogram.header {
height: 150px;
margin: -30px 0;
}
.parallelogram.footer {
height: 150px;
margin: -30px 0;
}
.image{
background: url(http://placekitten.com/300/300);
background: blue;
width: calc(100% / 3);
height: 100%;
display: inline-block;
float: left;
border: 3px solid white;
box-sizing: border-box;
}
<div class="container">
<div class="parallelogram header"></div>
<div class="parallelogram">
<div class="image"></div>
<div class="image"></div>
<div class="image"></div>
</div>
<div class="parallelogram footer"></div>
</div>
