Site works cross-browser

To reach the most users, sites should work on every major browser.

# Recommendations

Test your site in Chrome, Edge, Firefox, and Safari, and fix any issues that appear in each browser.

If your page is a Progressive Web App, consider using Workbox, a high-level service worker toolkit. Workbox is developed against a cross-browser test suite, and when possible, automatically falls back to alternative implementations of features that are missing from certain browsers:

• The workbox-broadcast-cache-update module uses the Broadcast Channel API if possible and falls back to a postMessage() implementation.
• The workbox-background-sync module uses the Background Sync API if possible and falls back to retrying queued events each time the service worker starts up.
