Global Styles in Storybook

How to set global styles in Storybook environment.

Via Addons

There are some addons that allow you to set global styles. One that I use is addon-backgrounds. It allows you to set background colors to have your components appear upon.

To use it (or other style-affecting addons), install:

npm install @storybook/addon-backgrounds

Then register their existence inside .storybook/addons.js:

import '@storybook/addon-backgrounds/register'

In your stories/index.js file, you can use it as a decorator:

import backgrounds from '@storybook/addon-backgrounds'
import { storiesOf } from '@storybook/react'

const bg = backgrounds([
  { name: 'product color', value: '#181818', default: true }

storiesOf('something', module).addDecorator(bg)
  .add('here', _ => {})

Via Head

If you don't have an addon at your disposal that makes adding a global style nicely controlled and declarative via a decorator, you can go the old-fashioned route and add your styles to the head.

You could do this in order to setup up an environment that has a proper font face on the page or to set up a reset stylesheet.

Create and edit a file called .storybook/preview-head.html and put whatever would usually go in the head here:

<link rel="stylesheet" href="" />

What other ways do you setup global styles or other environmental properties for your Storybook stories?
