Description

Example demo at https://codepen.io/Krinkle/pen/RwGJLzJ

On mediawiki.org, the property scroll-margin-top is currently stripped out. Presumably due to being unknown.
The property is part of CSS Scroll Snap Module Level 1, a W3C Candidate Recommendation.

Browser support:
Scroll snap support ranges from 95% (in 2021) for the popular properties (of earlier drafts) and 0-20% support for the newer less popular properties.
