One container with four or more divs inside that line up like a perfect puzzle and the last div fills out the remaining height..
the image illustrates how it should look like
where I am at: http://jsfiddle.net/meb9h3vx/
.wrap {
float: left;
background: #fff;
width: 100%;
}
.get2 {
float: left;
height: auto;
width: 50%;
}
<div class="wrap">
<div class="get2">
<h1>1</h1>
abc
</div>
<div class="get2">
<h1>2</h1>
</div>
<div class="get2">
<h1>3</h1>
d
<br>e
</div>
<div class="get2">
<h1>4</h1>
</div>
</div>
