Programmatically adjust the [preview `<head>`](../../configure/story-rendering.mdx#adding-to-head) of your Storybook. Most often used by [addon authors](../../addons/writing-presets.mdx#ui-configuration).

If you don't need to programmatically adjust the preview head, you can add scripts and styles to [`preview-head.html`](../../configure/story-rendering.mdx#adding-to-head) instead.
|
|
</Callout>
|
|
|
|
For example, you can conditionally add scripts or styles, depending on the environment:
|
|
|
|
{/* prettier-ignore-start */}
|
|
|
|
<CodeSnippets path="main-config-preview-head.md" />
|
|
|
|
{/* prettier-ignore-end */}
