Open this example in a new tab: phase banner
HTML
<div class="govuk-phase-banner govuk-width-container">

    <strong class="govuk-tag govuk-phase-banner__content__tag">
      Alpha
    </strong>

    </span>
  </p>
</div>
Nunjucks
Nunjucks macro options

Use options to customise the appearance, content and behaviour of a component when using a macro, for example, changing the text.

Some options are required for the macro to work; these are marked as “Required” in the option description. Deprecated options are marked as “Deprecated”.

If you’re using Nunjucks macros in production with “html” options, or ones ending with “html”, you must sanitise the HTML to protect against cross-site scripting exploits.

Primary options
Name Type Description
text string Required. If html is set, this is not required. Text to use within the phase banner. If html is provided, the text option will be ignored.
html string Required. If text is set, this is not required. HTML to use within the phase banner. If html is provided, the text option will be ignored.
tag object Required. The tag used by the phase banner component. See macro options for tag.
classes string Classes to add to the phase banner container.
attributes object HTML attributes (for example data attributes) to add to the phase banner container.

When to use this component

Services hosted on a service.gov.uk domain must use the phase banner until they pass a live assessment.

How it works

There are 2 ways to use the phase banner component. You can use HTML or, if you are using Nunjucks or the GOV.UK Prototype Kit, you can use the Nunjucks macro.

Use an alpha banner when your service is in alpha, and a beta banner if your service is in private or public beta.

Show the Phase banner inside the <header> element, directly after either:

If you use Nunjucks, use the headerEnd block to place the Phase banner on your page.

See ‘Add extra content at the start or end of the <header> element’ in ‘Page template: Blocks and options’.

Phase banners are shown across all pages of a service, so users should understand it as a service-level message.

You can choose to place the Phase banner in a more appropriate place for your service, however you’ll need to customise the component and provide your own CSS code to make it show correctly.

Collect feedback from users

Use the Feedback component to ask users to give feedback about your service and provide them with a link a feedback page.

Find out what feedback you need to collect at each phase in the GOV.UK Service Manual.
