Promptu 
A micro CSS-in-JS library that provides shorthands for commonly-used CSS rules as well as utility functions for transforming and parsing between CSS-compatible data types. For documentation please visit here.
Setup
$ npm install
# Run tests (against TypeScript source files)
$ npm test
# Build the library
$ npm run buildUsage
Promptu pairs well with Styled Components (or any other CSS-in-JS library). Example use:
import { align, container } from 'promptu'
const StyledRoot = styled.div`
${align.ftl} // Aligns to top left in fixed position
${container.fvtl} // Transforms this div into a flex box where children are vertically top left aligned
`Normalizing Styles
A raw CSS file for just normalizing rules is generated and packaged into the released module at lib/normalize.css, which you can access directly via unpkg.
