The App Footer is a universal component designed to provide essential links and content at the bottom of the application.
Usage
When to use
- On every screen of an application where universal links or content are required.
Order of content
While the Ember component allows flexibility in the ordering of links and content, we recommend the following structure for a consistent visual appearance across applications:
- StatusLink
- LegalLinks
- Additional links
- Plain text items (or metadata, such as version numbers)
- Copyright
Status link
The StatusLink is used to communicate the application status via a third-party service or tool (such as statuspage.io). If needed, the status can be customized to suit the specific product needs.
Legal links
A set of standard legal links are provided by default. These are recommended for customer-facing products, but can be turned on/off within the component as needed.
Additional links
Additional links can be added as necessary. Common examples may include linking to a changelog, GitHub, etc.
Plain text items
Plain text content can be added after the links. This is often used for displaying the version number or other metadata related to the product.
Extra content blocks
Extra content blocks are available before the list of links and before the copyright.
The extra content block can be used to add quick interactions that change the whole application, e.g., a theme switcher.
Avoid adding information that's critical to the user's journey in the App Footer.
Themes
The App Footer supports both Light
and Dark
theme options. The dark theme can be used when there is a need for a footer on a dark background, e.g., a loading screen, but it should be used sparingly.
Responsiveness
In Figma, we support two size variants, Large
and Small
, to help illustrate how the component will respond to different viewport sizes. In code, the component is responsive.
Large
The Large
size accounts for most larger viewport sizes and, depending on the number of links and additional content, will display elements in a single row or wrap as the viewport size is reduced.
Please note, this screenshot is reduced in size to fit within the content container of the website.
Small
How to use this component
The AppFooter
is used to display a brief list of useful links and information relevant to an entire application.
Basic invocation with recommended content
The AppFooter
contains only a copyright by default. The provided LegalLinks
child component is recommended for inclusion in application footers for our cloud products such as HCP and TFC.
<Hds::AppFooter as |AF|>
<AF.LegalLinks />
</Hds::AppFooter>
StatusLink
Add the StatusLink
to display information on the health of your application. Pass a predefined status
name or use individual arguments to set text
, statusIcon
, iconColor
to create a custom status type. Pass a custom href
value to point to a custom URL.
<Hds::AppFooter as |AF|>
<AF.StatusLink @status="operational" />
</Hds::AppFooter>
Link
You can add custom links in addition to or instead of including LegalLinks
.
<Hds::AppFooter as |AF|>
<AF.Link
@href="https://cloud.hashicorp.com/docs/changelog"
>Changelog</AF.Link>
</Hds::AppFooter>
Item
Item
components can be used to include meta text or other non-link content.
<Hds::AppFooter as |AF|>
<AF.Item>
<Hds::Text::Body @tag="span" @size="100">v.2.0</Hds::Text::Body>
</AF.Item>
<AF.Item>
<Hds::Text::Body @tag="span" @size="100">Vault</Hds::Text::Body>
</AF.Item>
<AF.Item>
<Hds::Text::Body @tag="span" @size="100">API: 1.0</Hds::Text::Body>
</AF.Item>
</Hds::AppFooter>
ExtraBefore & ExtraAfter
Custom content can be added either before or after the AppFooter
main content. The layout of this content is inline with other content by default.
<Hds::AppFooter as |AF|>
<AF.ExtraBefore>
<Doc::Placeholder @text="Extra Content Before" @height="2em" @width="fit-content" class="doc-app-footer-demo-placeholder" />
</AF.ExtraBefore>
<AF.LegalLinks />
<AF.ExtraAfter>
<Doc::Placeholder @text="Extra Content After" @height="2em" @width="fit-content" class="doc-app-footer-demo-placeholder" />
</AF.ExtraAfter>
</Hds::AppFooter>
Custom layout
Add your own styles to customize the layout of the extra content areas.
<Hds::AppFooter as |AF|>
<AF.ExtraBefore>
<div class="doc-app-footer-demo-custom-content-layout">
<Doc::Placeholder @text="Extra Content Before" @height="2em" @width="fit-content" class="doc-app-footer-demo-placeholder" />
</div>
</AF.ExtraBefore>
<AF.LegalLinks />
<AF.ExtraAfter>
<div class="doc-app-footer-demo-custom-content-layout">
<Doc::Placeholder @text="Extra Content After" @height="2em" @width="fit-content" class="doc-app-footer-demo-placeholder" />
</div>
</AF.ExtraAfter>
</Hds::AppFooter>
Theme
Both a light
and a dark
theme are included.
<div class="doc-app-footer-demo-dark-background">
<Hds::AppFooter @theme="dark" as |AF|>
<AF.StatusLink @status="operational" />
<AF.LegalLinks />
</Hds::AppFooter>
</div>
