css flex family of properties

[graphicz]

Quite a bit of the resonsive designs in v14 appear ti have been built using the flex family of styles. http://www.w3schools.com/cssref/css3_pr_flex.asp

This method seems, however, not to work in firefox. I know many mobile devices do not primarily use FF as a browser although it is an option on iOs and android. Even the ZTE Firefox phone does not use FF as a default browser. It is worth bearing this in mind when using the FF developer tools responsive view.

I was having a play with flex to be able to custom edit some layouts and here is wher I am so far. Any suggestions on improvement welcome. The Media queries are a bit of a dogs dinner but they seem to work.
