DOMPointReadOnly.z

The DOMPointReadOnly interface's z property holds the depth coordinate, z, for a read-only point in space. If your script needs to be able to change the value of this property, you should instead use the DOMPoint object.

In general, positive values of z mean toward the user (out from the screen), and negative values of z mean away from the user (into the screen), assuming no transforms have resulted in a reversal.

Syntax

const zPos = someDOMPointReadOnly.z;

Value

A double-precision floating-point value indicating the z coordinate's value for the point. This value is unrestricted, meaning that it is allowed to be infinite or invalid (that is, its value may be NaN or Β±Infinity).
