Position div over other content - html

Question

I am using bootstrap and the page width is NOT fixed.
I would like to display a contact form div (grey box below) like this:
So the grey contact form is sort of floating over the blue and white divs.
Thanks!
Here's what I have been trying to do: http://jsfiddle.net/w69j4xam/
<div class="header">
Header
</div>
<div class="content">
<div class="bluediv">
Some text here
</div>
<div class="whitediv">
Some more text here
</div>
<div class="contactform">
Contact Form<br/><br/><br/><br/>
</div>
</div>
body{
padding: 20px;
}
.header{
height: 50px;
background-color: green;
}
.content{}
.bluediv{
height: 150px;
background-color: #AFEEEE;
}
.whitediv{
height: 180px;
background-color: #FFF;
}
.contactform{
background-color: grey;
width: 100px;
position: absolute;
}

Answer 1

In terms of your jfiddle example, all you need to add is a right and a top.
.contactform{
right:50px;
top:100px;
background-color: grey;
width: 100px;
position: absolute;
}

Answer 2

Position the outer div however you want, then position the inner divs using absolute. They'll all stack up.
<style type="text/css">
.inner {
position: absolute;
}
</style>
<div class="outer">
<div class="inner">1</div>
<div class="inner">2</div>
<div class="inner">3</div>
<div class="inner">4</div>
</div>
