It would be good to learn Bootstrap for this, though it’s not mandatory. In Bootstrap you could just define it like this:
<div class="container">
<div class="row">
<div class="col-md-4">Content 1</div>
<div class="col-md-4">Content 2</div>
<div class="col-md-4">Content 3</div>
</div>
</div>
A basic way to do this without Bootstrap is here: http://jsfiddle.net/7Zs9f/1/
