While you can still use this package, I recommend giving my emotion based package called styled-velocity-emotion a shot. I'll update this one when I have time. It's smaller, faster, better.
Styled-Velocity, a React-based styled prop and UI library to increase your velocity and help build your Design System.
yarn add styled-velocityor
npm install styled-velocityImport example:
import { appearanceProps, cssProps, dimensionProps } from 'styled-velocity'- Overview - docs
All of the following have access to the sharedProps.

All of the sharedProps can take a single value, or an object of Breakpoints. You have all the choices you could possibly use for creating style within breakpoints. This system is mobile first, but there's several ways to mix it up.
Let's using the width css property for the following examples...
w={50}If you want to create a breakpoint, supply an object, and use the key as the breakpoint. Make sure to give the lowest a 0, if it's min-width 0, it won't wrap it in a media query.
w={{ 0: 50, 768: 100, 1024: 150 }}returns
width: 50px;
@media (min-width: 768px) {
width: 100px;
}
@media (min-width: 1024px) {
width: 150px;
}If you want to create a breakpoint that has min and max, supply a key that is a string like so...
w={{ '768-1024': 100 }}returns
@media (min-width: 768px) and (max-width: 1024px) {
width: 100px;
}Pretty cool, eh?
This min-max string key is how the scaling pixel values work. If you wanted to scale anything from one pixel value to another, like font-size for instance, you can do this...
fontSize={{
0: 12,
'414-1023': { min: 12, max: 36 },
1024: 36
}}returns
font-size: 12px;
@media (min-width: 414px) and (max-width: 1023px) {
A css formula to scale the font-size from 12px to 36px based on screen width
}
@media (min-width: 1024px) {
font-size: 36px;
}Notice the conversionType? This should clue you into what is possible for the given prop.
You can pass is an int like 50 and it'll convert to 50px. You can pass it a fraction, like 1 / 2 and it'll convert to a 50%. You can also just pass a string like 50em.
Used for grow and shrink, if you pass true, it'll convert to 1 for css purposes. And false to 0.
This takes an int and converts it to the cells width (or height). Thus cw={2} makes the element 2 cells wide (based on your grid config).
Similar to getCells, but takes an object. ctransform={{ 0: {x: 0.5, y: 0} }} would offset the x coords of the element by 1/2 cells width.
Flex has some pretty unintuitive properties. For instance, valign="top" refers to the vertical alignment an element (assuming you staying with direction=row). You can of course pass the original css flex properties as well if you are used to them.
| input | output |
|---|---|
| top | flex-start |
| left | flex-start |
| start | flex-start |
| bottom | flex-end |
| right | flex-end |
| end | flex-end |
| middle | center |
| center | center |
In order to use this package on IE, you'll need a polyfill for String.prototype.includes. You can do this with loading a polyfill script from https://polyfill.io/, such as
<script src="https://polyfill.io/v3/polyfill.min.js?features=String.prototype.includes" async></script>
With Next.js you can load polyfills another way. See https://github.com/zeit/next.js/blob/canary/examples/with-polyfills/client/polyfills.js.
Add following to client/polyfills.js
/*
* This files runs at the very beginning (even before React and Next.js core)
* https://github.com/zeit/next.js/blob/canary/examples/with-polyfills/client/polyfills.js
*/
/* eslint no-extend-native: 0 */
// core-js comes with Next.js. So, you can import it like below
import stringIncludes from 'core-js/library/fn/string/virtual/includes'
// Add your polyfills
String.prototype.includes = stringIncludesAnd then modify the next.config.js
// next.config.js
const nextConfig = {
webpack(config) {
/*
* Add polyfills
* https://github.com/zeit/next.js/blob/canary/examples/with-polyfills/next.config.js
*/
const originalEntry = config.entry
config.entry = async () => {
const entries = await originalEntry()
if (entries['main.js'] && !entries['main.js'].includes('./client/polyfills.js')) {
entries['main.js'].unshift('./client/polyfills.js')
}
return entries
}
return config
},
}
module.exports = nextConfig
