Mobile Responsive Design Broken on Replit

App displays incorrectly on mobile devices with layout breaking, text too small, or elements overlapping. Responsive design isn't working.

Missing viewport meta tag or CSS media queries cause mobile rendering issues.

Common Causes

  1. Missing viewport meta tag in HTML head
  2. Fixed width CSS instead of flexible
  3. No CSS media queries for mobile breakpoints
  4. CSS not loaded on mobile due to caching
  5. Images not responsive (missing max-width: 100%)

How to Fix It

Add to all HTML templates. Use CSS media queries or Tailwind/Bootstrap for responsive design. Set img { max-width: 100%; } for images. Test with Chrome DevTools mobile emulation. Use flexible units (%, em, rem) instead of fixed pixels.
