Accessibility statement

The site’s approach to keyboard access, responsive layouts, readable structure and accessibility feedback.

Our approach

The site uses semantic headings, keyboard-accessible navigation, visible focus, responsive layouts, text alternatives for meaningful images and a skip link.

Known limitations

External websites and advertising are controlled by their own providers. Some browser or assistive-technology combinations may render features differently.

Feedback

Report an accessibility barrier through the publisher help desk linked on the Contact page. Include the page URL, device, browser and the difficulty encountered.
