Mobile web

58Fair

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture123
  1. Double announcement banner — Two stacked banner messages eat ~25% of the first viewport and push the primary CTA below the fold.
  2. View Leaderboards button — Primary CTA sits far below the first viewport; visitors must scroll past stats cards to find any action.
  3. Oversized logo lockup — Full wordmark plus Princeton crest bloats the header, spending vertical space the hero needs.

Does the design help or inhibit what the page is trying to say?

Information hierarchy annotations on the desktop capture1234
  1. Top navigation bar — Eleven equal-weight links plus two logo exits leak attention before the hero headline registers.
  2. Double announcement banner — Two stacked banner messages with underlined links compete with the value prop and add two more exits.
  3. Paper link in subhead — Blue 'here' link embedded in the subtitle pulls readers off-page before they reach View Leaderboards.
  4. GitHub secondary button — Sits at nearly the same size and position as the primary CTA, splitting the click decision.
