Mobile web

56Fair

The phone experience as a first-class citizen.

Mobile web annotations on the mobile capture1234
  1. Collapsed mobile header — The desktop "SIGN UP FREE" CTA was dropped in the collapse, leaving zero primary action in the entire mobile fold.
  2. Accessibility bubble — Floats directly over the Google logo, truncating it to "oogle" and undermining the trust row.
  3. Shield badge overlay — Overlaps the "Cesium at SIGGRAPH 2026" card heading, clipping the first character of both lines.
  4. Empty search pill — A blank white input sits beside a separate search icon, looking like a broken duplicate control in the header.

Copy, size, verb, cost-feel — does the primary CTA earn the click?

Problems

  • no CTA in hero, nav-corner only
  • no CTA visible on mobile fold
  • small footprint vs headline
  • 'sign up' signals a form, not value
