DOMPoint.x

The DOMPoint interface's x property holds the horizontal coordinate, x, for a point in space.

In general, positive values x mean to the right, and negative values of x means to the left, barring any transforms that may have altered the orientation of the axes.

A double-precision floating-point value indicating the x 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 ±Infinity).

• The other coordinate properties: y, z, and the perspective value, w.
