Best Practices for Responsive Images in HTML and Next.js

Implementing responsive images from scratch can be complex. Frameworks like Next.js simplify this drastically.

The Next.js Image Component

The next/image component automatically optimizes images on-demand. It serves WebP/AVIF formats, generates multiple sizes for responsive delivery, and implements lazy loading by default.

import Image from 'next/image';

export default function Hero() {
  return (
    <Image src="/hero.jpg" alt="Hero" fill priority />
  );
}
