If a single value is specified in the background-position property, the browser applies that value to both the horizontal and vertical position.This statement is : TRUE

A direction or plane traveling by a specific point is considered to be vertical in astronomy, geography, and other relevant fields and settings if it contains the local gravity direction at that location.

On the other hand, if a direction or plane is perpendicular to the vertical direction, it is said to be horizontal. A vertical object, like the y-axis in the Cartesian coordinate system, can typically be drawn from up to down (or down to up).

The earth's surface is vertical and any plane parallel to it is also vertical under the flat earth scenario, where the earth is conceptually a huge (infinite) flat surface with a gravitational field at a right angle to the surface.
