# Tabs

The tab navigation and content tabs share the same styling. The tab navigation uses links to
navigate between pages, whereas the tab list uses `<buttons>` to toggle content on a single page.

Tabs should be displayed on the `background-alt` color, with their content area set to background
and 1rem of padding on the left and right.

<Primary />
<Controls />

## Content Tabs

<Canvas of={stories.ContentTabs} />

## Navigation Tabs

<Canvas of={stories.NavigationTabs} />

## Content tabs in dialogs

Tabs can be used in dialogs to separate related content.

<Canvas of={dialogStories.TabContent} />

## Accessibility

**Navigation tabs** are implemented using the `<nav>` element and `<a>` for each tab.

**Content tabs** should be implemented with the `tablist` role and:

- Use `<button>` for the tab elements
- Set `aria-selected` for each tab; “true” for selected and “false” for unselected
- See WCAG for more: https://www.w3.org/TR/wai-aria-practices/examples/tabs/tabs-1/tabs.html
