Tailwind Responsive
// Mobile-first: base styles, then scale up
<div className="
w-full // mobile: full width
sm:w-1/2 // 480px+: half
md:w-1/3 // 768px+: third
lg:w-1/4 // 1024px+: quarter
">
// Responsive grid
<div className="grid grid-cols-1 sm:grid-cols-2 lg:grid-cols-3 xl:grid-cols-4 gap-6">
// Responsive typography
<h1 className="text-3xl md:text-4xl lg:text-5xl">
// Show/hide by breakpoint
<div className="block md:hidden">Mobile only</div>
<div className="hidden md:block">Desktop only</div>
Fluid Typography
h1 { font-size: clamp(2rem, 5vw, 4rem); }
p { font-size: clamp(1rem, 2.5vw, 1.25rem); }
Touch Targets
- Minimum 44x44px for all interactive elements
- Use
touch-manipulationto prevent 300ms tap delay - Adequate spacing between targets
<button className="min-w-[44px] min-h-[44px] touch-manipulation">
Mobile Simplification
| Desktop | Mobile |
|---|---|
| Full nav bar | Hamburger menu |
| Side-by-side fields | Stacked fields |
| Multi-column grid | Single column |
| Inline buttons | Fixed bottom bar |
| Data table | Collapsed cards |
| Visible sidebar | Hidden/collapsible |
Images
// Responsive images
<img
srcSet="image-400w.jpg 400w, image-800w.jpg 800w, image-1200w.jpg 1200w"
sizes="(max-width: 640px) 100vw, (max-width: 1024px) 50vw, 33vw"
