Improving Accessibility
The Hosted Payment Page page can provide a user experience compliant with the Web Content Accessibility Guidelines (WCAG) 2.0 Level AA accessibility standard. Study the WCAG 2.0 guidelines and ensure that your web site conforms to them.
To ensure that your integration is accessible, set your checkout page language by adding the lang attribute to the <html> element of the page:
<html lang="en">
<head></head>
<body></body>
</html>
