In this tutorial I will show you some possibilities, CSS flexible boxes offer you. They are especially useful in context of responsive design and are more and more supported by newer browsers, as well in the desktop world.
I advice to check out my tutorial about CSS floating and clearing:

For further informations on the flexbox, have a look at CSS- Tricks: http://css-tricks.com/snippets/css/a-guide-to-flexbox/
As always, I used JSBin for this tutorial.
