Glamorous is my favorite CSS-in-JS library for React and React Native. Coupled with styled-system, polished and prop-styles, it brings you the most complete and flexible approach to component styling. Among the many reasons to prefer Glamorous, is the ability to use JSX props for styling and not having to… Let’s take a look at an example of what I mean: <Box flex={1} justify="center" align="center"> {/*...*/} </Box> See? I didn’t have to name this particular instance of Box, and there’s only a couple of style overrides I was interested in, I didn’t have to create a new component for it.
