Modelberry CSS Theme

Library for working with css theme variables.

About

The library takes an object and converts it to css variables. It was designed to be used with Storybook and Gatsby but can be used with any other javascript framework.

Example theme

This example contains only a few colors but any css value can be used.

export const myTheme: ThemeProps = {
  color: {
    rock: {
      100: '#e0e0e0',
      200: '#b0b0b0',
      300: '#909090',
    },
  },
}

This results in the css variables: color-rock-100, color-rock-200 and color-rock-300.

Gatbsy

To use the library with Gatbsy, create a typescript file like this:

import { setCssVars } from '@modelberry/css-theme/plain'
import { myTheme } from './my-theme'

setCssVars({ theme: myTheme })

Compile this to javascript (by using e.g. Rollup's umd format) and tell Gatsby to load this in gatsby-ssr.js:

export const onRenderBody = ({ setPreBodyComponents, setHeadComponents }) => {
  setPreBodyComponents([
    <script key="1" type="text/javascript" src="/set-css-vars.js" />,
  ])
}

Storybook

A StyleElement is provided that can be used with e.g. Storybook.

import { Story } from '@storybook/react'
import { StyleElement } from '@modelberry/css-theme/react'
import { myTheme } from './my-theme'

export const ThemeDecorator = (Story: Story<any>) => {
  return (
    <>
      <StyleElement theme={myTheme} />
      <Story />
    </>
  )
}
