🆕 New features

Add a modifier class for header inline search or account links

We've added a new .nhsuk-header--inline class and inline Nunjucks option for the header component. This positions the search bar (or account links) inline with the NHS logo on small screens, depending on the length of your service name. For example:

  {{ header({
+   inline: true,
    account: {
      items: [
        {
          text: "Log in",
          href: "/log-in"
        }
      ]
    }
  }) }}

This was added in pull requests #1783: Add support for inline header search or account and #1801: Add Nunjucks options for components with modifier classes.
