Contents can be used for various things.

- On page contents lists
- Side menu for section links
- Side menu for on page content anchor links

The default component should be used as an inline list of links to other parts of the page.

This can be modified with the `.sta-contents--menu` class to use as a side menu.

## Vertical margins

By default the contents block has top and bottom margins. This can be removed using the following modifiers:

- `.sta-contents--collapse` removes top and bottom margins.
- `.sta-contents--collapse-top` removes top margin only.
- `.sta-contents--collapse-bottom` removes bottom margin only.

## Contents heading

An optional heading can be included at the top of the contents list of links. If no heading is present then an aria-label attribute should be included to describe the purpose of the `<nav>` block.
