Responsive Design Strategies for Modern Web Apps

With foldables, 8K monitors, and everything in between, responsive design means more than fluid grids—it’s performance, accessibility, and device‑specific UX baked into every component.

Core Pillars

• Mobile‑First CSS: Ship the lightest possible experience, then enhance via media & container queries.
• Progressive Hydration: Use React Server Components or Islands Architecture to delay JS where possible.
• Smart Assets: AVIF/WebP via <picture> and srcset, lazy‑load everything below fold.

Dev Toolbox

• Tailwind CSS + CSS Variables for rapid theming.
• Next.js  for built‑in optimization and blur placeholders.
• Lighthouse CI to budget performance in every pull request.

The best responsive sites feel native on any screen size—and they ship only the bytes each device needs.
