Values
- auto

- none
- Touches that begin on the element MUST NOT trigger default touch behaviors.
- pan-x
- The user agent MAY consider touches that begin on the element only for the purposes of horizontally scrolling the element’s nearest ancestor with horizontally scrollable content.
- pan-y
- The user agent MAY consider touches that begin on the element only for the purposes of vertically scrolling the element’s nearest ancestor with vertically scrollable content.

- The user agent MAY consider touches that begin on the element only for the purposes of scrolling and continuous zooming.
Examples
You might find the following example within a fingerpainting application to ensure that its canvas doesn’t move when a user touches and manipulates it. When a user touches this canvas and moves his or her finger, no manipulation will occur. DOM events will be sent instead.
canvas#fingerpainter {
touch-action: none;
}
The application has content that extends horizontally beyond the viewport and the desired behavior is to allow the user to scroll content left and right as desired without the browser moving the entire page.
<div style="touch-action: pan-x;">
This element receives pointer events when not panning in the horizontal direction.
</div>
