Mobile Accessibility Criteria Is there sufficient contrast? Is pinch zoom supported? Using screen reader: Are images described? Can you complete all actions? Do pop-ups have a close button? Does focus move to a pop-up rather than continue through the rest of the page? Is all content and functionality available by swiping left and right and up and down?
