DOMPointReadOnly: x property
Note: This feature is available in Web Workers.
The DOMPointReadOnly interface's
x property holds the horizontal coordinate, x, for a
read-only point in space. This property cannot be changed by JavaScript code in this
read-only version of the DOMPoint object.
In general, positive values x mean to the right, and negative values of
x means to the left, assuming no transforms have resulted in a reversal.
Value
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).
