React Layout Components
npm install react-layout-components
Useful, Modern and universal layout Components for React.js based on flexbox.
The basis <Box> Component is highly inspired by React Native's Flexbox implementation and though accepts almost the same props. It supports all flexbox specifications and automatically adds alternative values and prefixes thanks to inline-style-prefix-all if needed.
Note: If you're not familiar with Flexbox at all, I recommend css-tricks 'Complete Guide to Flexbox' which is an awesome source for beginners as well as a nice refreshment for experts.
Components
To be able to use any of those Components below, make sure you have added the following CSS class somewhere. Personally I just inline it inside the <head> of the index.html.
.react-layout-components--box {
display: -webkit-box;
display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
}
Note: This is a temporary fix and will hopefully be removed if React merges https://github.com/facebook/react/pull/6701.

<Box width={300} height={500}>
//This acts as an actual flexbox container
<Box justifyContent="center" alignItems="flex-start">
<Box flex={3}>Flex 3</Box>
