CSS anchor positioning — 15 Jan 2026

Believe it or not, I only found out about Jake Archibald explainer videos on Firefox for Web Developers YouTube channel.

I stumbled upon a Bluesky post presenting CSS Anchor Positioning in my Tapestry feed. Not only was I blown away and excited by the feature, but also by the quality and production value of the YouTube Short. It really livens up the post, and highlights the feature in a engaging way. Love it. Check-out the others.

Jake is an amazing speaker. He always delivers an original talk, full of resources an insights in a clear and passionate way. I’ve been fortunate to meet him and enjoy his talks at several conferences over the years.

✱ He’ll be taking at SmashingConf Freiburg this year.

CSS Anchor positioning allows placing elements anywhere on the page relative to an “anchor element”, without regard to the layout of other elements besides their containing block.
