I have created a simple, light weight, GUI similar to Microsoft Metro UI. It is comprised of a set of elements which are floating to make it flexibly re-sizable according to the size of the screen:

Here is the code:

I have a problem positioning the icon elements in the divs. This is what I have:

and this is what I want:

In other words I want to be able to position the elements in the tiled div elements absolutely. I tried various CSS positioning techniques (relative, fixed, absolute) but couldn’t solve it. I suspect it’s because the tiles are floating elements?
How can I be able to design the contents of each tile regardless of its position in the web page?
Make the tile divs relatively positioned and icons absolutely positioned.
With relative positioning the tile div becomes a containing block for its absolute positioned children. Relative elements are positioned just like normal (static) elements when top and left are zero or undefined.
