Prioritize the essential action
A phone visitor should quickly understand your offer and find the contact, booking or purchase action. Keep headings readable and touch targets comfortable.
Design for real content
Test long titles, email addresses, menus and forms on narrow screens. Avoid layouts that require horizontal scrolling.
Check usability as well as appearance
Keyboard access, clear form labels and reduced-motion support help more people use the site. Test the full journey, not only the homepage.
