# Custom CSS

Administrators can supply custom CSS that overrides elements of their site's pages. The settings live in the Admin Dashboard under *Admin Settings > Branding > CSS*.

Before changing a site's CSS, review the ExaVault Site Branding documentation. Many appearance options are already configurable there without writing CSS.

This is an advanced feature. Incorrect CSS definitions can make the site unusable.

The following example reduces the padding on the tabs at the top of the Site Branding configuration screen, producing a slightly more compact tab strip:

```
.nav > li > a {
  padding: 5px; 5px;
}
```

The full collection of CSS selectors is available at `https://[your_domain]/ftp/static/css/site.css`.
