HTML5 Advent is an independent publication of web platform guides. If something here is wrong or has stopped being true, we would rather hear it than leave it standing.
There is no form on this page and no third-party service in between: the link opens your own mail client, and nothing you type is sent to this site.
What is worth writing about
- Factual corrections. A browser that changed its behaviour, an API that shipped or was removed, a snippet that no longer runs. Include the page URL and the browser version you tested with — it makes the fix much faster.
- Questions a guide should have answered. Those gaps usually mean the guide needs work, and they are the most useful thing you can send.
- Rights and attribution concerning anything published here.
