To prevent stale CSS after a deployment, you need a cache-busting strategy that generates versioned asset URLs so browsers re-fetch updated style files instead of reusing cached versions.

Cache busting is the process of forcing browsers to fetch the latest static assets by changing their URLs or headers. You need it when users see outdated CSS because browsers cache static files aggressively across deployments.

You can implement cache busting without a bundler by manually generating versioned asset URLs in your HTML references or applying equivalent cache-busting headers during your release workflow to safely invalidate client caches.

Yes, you can use versioned URLs to invalidate browser caching for static web projects. By appending a version string to your CSS file references, you ensure browsers deterministically fetch the new version after each release.

Updated CSS may not show up because browsers cache static assets aggressively, causing styling changes to appear delayed or broken across deployments without proper cache-busting headers or versioned URLs.

The best way to ensure browsers fetch new CSS files is to implement a cache-busting strategy that generates versioned URLs or equivalent headers, guaranteeing every visitor sees the update immediately after the release without a hard refresh.
