NatSkin Flexbox

Flexbox is a layout model for arranging items (horizontally or vertically) within a container, in a flexible and responsive way. Flexbox makes it easy to design a flexible and responsive layout, without using float or positioning.

There is a set of CSS classes part of NatSkin to help with CSS Flexbox Layouts. Note that all classes use the foswikiFlex... prefix as they are of general use not restricted to NatSkin.

A flexbox layout consists of a container and its items. There are classes to be used on a container and some that only make sense for child items within that container:
