Legacy CSS Scroll Snap syntax support has been dropped

Published: | Categories: CSS


Firefox 68 has implemented the latest CSS Scroll Snap spec that has been revised significantly since the initial implementation was shipped with Firefox 39. While Chrome and Safari have already added the support for the new syntax, the changes in Firefox are not backward-compatible:

  • The scroll-snap-coordinate, scroll-snap-destination, scroll-snap-type-x and scroll-snap-type-y properties have been dropped
  • The scroll-snap-type property has become a longhand, so the old shorthand syntax like scroll-snap-type:mandatory will stop working

Be sure to update your stylesheets accordingly for the new syntax if you have already utilized Scroll Snap.
