Lesson 2 of 6 · Mobile
Set the viewport and make buttons easy to tap
What it is
The viewport tag tells phones to fit the page to the screen. Buttons and links need enough size and space to tap accurately (about 44 × 44 pixels).
Why it matters
Tiny, crowded links cause mis-taps and frustrated visitors leaving.
✓ Good example
Large 'Call now' and 'Book online' buttons with space between them.
✗ Common mistake
Footer links so close together you hit the wrong one.
You pass when: Page fits the screen and buttons are comfortably tappable.
