I've played with it a bit and it's quick and dirty as I didn't have a lot of time.
If you want proper calculations you have to NOT mix percentages and px/em etc. Margins (right and left) can be expressed as % of the width and with the proper box model applied see Pen.
You can just add up the the percentages and make sure they don't exceed 100%.
I have done a little bit of looking around, and banging on some code but can't quite figure it out.
The Pen is here: http://codepen.io/GAtkins/pen/yCmxH
How do I center the the divs inside the green container in a flexible layout?
Any help will be greatly appreciated and thanks in advance.
