ScrollTimeline: axis property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The axis read-only property of the ScrollTimeline interface returns an enumerated value representing the scroll axis that is driving the progress of the timeline.

Value

An enumerated value. Possible values are:

"block": The scrollbar on the block axis of the scroll container, which is the axis in the direction perpendicular to the flow of text within a line. For horizontal writing modes, such as standard English, this is the same as "y", while for vertical writing modes, it is the same as "x".
"inline": The scrollbar on the inline axis of the scroll container, which is the axis in the direction parallel to the flow of text in a line. For horizontal writing modes, this is the same as "x", while for vertical writing modes, this is the same as "y".
"y": The scrollbar on the vertical axis of the scroll container.
"x": The scrollbar on the horizontal axis of the scroll container.
