# Snippets

> Reusable single-purpose JS + CSS units.

A **snippet** is a small, reusable bit of paired JS and CSS: a sticky header, a custom form interaction, a smooth-scroll behavior. Build it once, install it on every site that needs it.

## Browse the global library

Cairn ships with a curated set of public snippets. Browse them in **Library → Snippets** and click **Install to team** to fork one into your workspace.

## Build your own

From a team's library page, click **+ New snippet** to author your own. Your team's snippets are private by default; you can flip them to public to share with the broader Cairn community.

## Install to a site

From any snippet detail page, click **Install** and choose which sites in your workspace should load it. Scope rules carry over from the snippet definition.
