The USA Banner uses predefined variables from a theme's global tokens to determine the default width of its content and gutters (padding).

For most applications this should be sufficient, but for others with custom layouts it can result in the banner's content appearing misaligned with the content of the rest of a page. To fix this, you can customize the --usa-banner__max-width and --usa-banner-gutter-width variables to match the application's page width and gutter width.

To illustrate how this works, here's an example of how to customize the banner's width and gutter width for an application with more narrow content:

/* These values can be whatever you need them to be */
:root {
  --usa-banner__max-width: 600px;
  --usa-banner-gutter-width: 1rem;


When to use

  • To identify as an official government site. Most government sites should use the banner.

When to consider alternatives

  • If you don't use a .gov domain and HTTPS. The banner text identifies .gov domains and HTTPS as indicators that a website is an official government website. Use the banner only if your site uses both the proper TLD and HTTPS.
  • Any time it would be misleading. The banner should be used to reduce confusion. Avoid using the banner on any site meant only for testing or otherwise not meant to be identified as an official government website.


  • Use the provided text without customization. The banner is most effective as an identifier and a learning tool when its message is consistent across government websites.
  • Show the banner on every page. Use the banner at the top of every page of a site. It can be confusing or misleading if it appears on some pages and not others.
  • Avoid distraction. The banner appears on every page of your site. Choose background colors that fit with your site theme and avoid color combinations that draw excessive attention to the banner.
  • Keep the text up-to-date. Use the most current version of the banner.
