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.

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. 
{% from "govuk/components/phase-banner/macro.njk" import govukPhaseBanner %}

{{ govukPhaseBanner({
  tag: {
    text: "Alpha"
  },
  html: 'This is a new service. Help us improve it and <a class="govuk-link" href="#">give your feedback by email</a>.'
}) }}

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 directly under either:

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.

WCAG 2.2

Do not make the phase banner ‘sticky’ to the top of the page by using `position: fixed` or any other method. This is to make sure it does not cover or obscure any content which has a focus applied. This is to comply with WCAG 2.2 success criterion 2.4.11 Focus not obscured (minimum).

Use a ‘feedback’ link to collect on-page feedback about your service. This can open an email or take the user to a dedicated page or form.
