Promo CTA
A full-width banner used to capture attention and prompt a primary action. Best suited to high-priority, time-sensitive calls to action.
When to use
- Use a promo CTA when you want to draw attention to one key action on a page, such as registering interest, signing up, or starting a featured journey
- Use one promo CTA per page. Its impact relies on being the single most prominent action
When not to use
- If the action is part of a serious or functional task, such as submitting a form or completing a payment, use a button instead. A promo CTA has a promotional feel that can undermine tasks the user needs to trust
Content guidance
- Write the label as a clear action. Start with a verb so the user knows what happens when they click
Accessibility
This component is designed with accessibility built in:
- The entire bar is a single clickable target, giving a large, easy to hit action area
- The arrow gives a visual cue of interactivity that does not rely on colour alone
- Focus state is designed and visible
- Colour contrast between the label and both the default and hover surfaces meets 4.5:1
When implementing, verify:
- The label alone describes where the link leads. If it does not, provide an aria-label that gives full context
- The component is announced as a link to assistive technology
