Design for priorities, not breakpoints
Mobile-first design forces a useful question: what matters most on this page? When space is limited, secondary content naturally moves down and the primary message and action rise to the top. That clarity benefits desktop visitors too.
Readable typography
Body text should be comfortably large, with generous line height and line lengths of roughly 60 to 75 characters on larger screens. Fluid type scales help headings stay proportionate across devices.
Touch-friendly interaction
Tap targets need enough size and spacing, important actions should sit within easy thumb reach and hover-only interactions should have touch equivalents.
Forms that work on phones
Use appropriate input types so the right keyboard appears, keep forms short, label every field clearly and show helpful error messages next to the relevant field.
Accessibility as part of responsiveness
Responsive sites should also respond to user preferences: zoomed text, reduced motion and keyboard navigation. Accessible design is simply good design for more people.
