Styling and CSS

There are many ways to include CSS in a web application, and correspondingly there are many ways to include CSS in Storybook. Usually it is best to try and replicate what your application does with styling in Storybook’s configuration.

CSS-in-JS

CSS-in-JS libraries are designed to use basic JavaScript. They often work in Storybook without any extra configuration. Some libraries expect components to be rendered in a specific rendering “context” (for example, to provide themes) and you may need to add a global decorator to supply it.

Importing CSS files

If your component files import their own CSS, Storybook’s webpack config will work unmodified with some exceptions:

• If you are using a CSS precompiler, you may need to add a preset (such as the SCSS preset, or add a loader to Storybook’s webpack config).

• In Angular, you'll need to take special care how you handle CSS:

  • Either customize your webpack config
  • Or use syntax to use a inline loader:

<CodeSnippets paths={[ 'angular/storybook-angular-inline-css-loader.js.mdx', ]} />

To use your CSS in all stories, you simply import it in .storybook/preview.js

Adding webfonts

If you need webfonts to be available, you may need to add some code to the .storybook/preview-head.html file. We recommend including any assets with your Storybook if possible, in which case you likely want to configure the static file location.
