Building Websites to Last: HTML First, CSS Second, JavaScript Last

Building websites for lasting functionality without CSS or JavaScript dependencies

From Hacker News Original Article Hacker News Discussion

A developer reflects on building web applications that endure over decades by prioritizing semantic HTML first, then layering CSS and JavaScript sparingly for enhancements. This approach ensures usability without relying heavily on fragile or complex dependencies.

Why it matters: Prioritizing HTML first ensures sites remain functional across browsers and devices for decades, enhancing longevity and accessibility.

The big picture: Modern CSS tools and minimal JavaScript progressively enhance user experience without breaking the core functionality.

The other side: Some argue JavaScript is indispensable today, especially with external libraries simplifying development and user interactivity.

Commenters say: Many appreciate the focus on longevity and simplicity but remain skeptical about eliminating JavaScript entirely, citing practical modern needs.
