Flexbox app – the interactive cheat sheet for Flexbox

Flexbox is a new CSS3 layout technology enabling developers to easily construct complex layouts. Before Flexbox, those layouts were difficult or impossible to achieve.

The Flexbox App is an interactive cheat sheet built with React. It allows you to try out all the new Flexbox attributes with instant visual feedback. Once you’re done playing around, you can use the tool to easily prototype actual Flexbox layouts - and soon also export the CSS!
