Description
These pseudo-classes match scroll markers that are, respectively, before or after the active marker (the one matching :target-current) within the same scroll marker group, as determined by flat tree order:
-
:target-before matches all scroll markers that precede the active marker in the flat tree order within the group.
-
:target-after matches all scroll markers that follow the active marker in the flat tree order within the group.
