Progressive Enhancement is a web development strategy that layers HTML, CSS, and JavaScript so that content remains accessible on any browser or device. Using a real-world example of a website tested on a Nokia 3310 with Opera Mini, the author demonstrates practical techniques: CSS Grid with graceful single-column fallback, ES2015+ JavaScript delivered only via type="module", WebP images with a picture element fallback, and native lazy loading with a noscript fallback. The core argument is that building on a solid semantic HTML foundation lets you use modern features freely while ensuring all users — regardless of browser capability — can access content.
