Responsive Layout System

Defaults

:root {
  --content: 72rem;
  --gutter: clamp(1rem, 4vw, 2rem);
}
.container {
  width: min(100% - 2*var(--gutter), var(--content));
  margin-inline: auto;
}

Breakpoints (example)

sm 640 · md 768 · lg 1024 · xl 1280
Design mobile structure first for content sites; desktop-first OK for dense tools

Rules

Prefer min, clamp, flex/grid over hard px pages
Avoid horizontal scroll on 360px width
Tables: cardify or scroll with shadow hints
Images: max-width:100%; height:auto

Pitfalls

Fixed 1440px mockups shipped as-is
Hover-only critical actions on mobile

Acceptance

360 / 768 / 1280 checked for main templates
