Which of the following property defines the y (vertical) coordinate for a positioned element, relative to the bottom of the enclosing object or browser window?

The correct answer is C. position.

The position property specifies the type of positioning used for an element. The possible values are static, relative, absolute, fixed, and sticky.

The static position is the default value. It means that the element will be positioned according to the normal flow of the document.

The relative position means that the element will be positioned relative to its parent element. The top, left, right, and bottom properties can be used to specify the position of the element relative to its parent element.

The absolute position means that the element will be positioned absolutely, relative to the viewport. The top, left, right, and bottom properties can be used to specify the position of the element relative to the viewport.

The fixed position means that the element will be positioned fixed, relative to the viewport. The top, left, right, and bottom properties can be used to specify the position of the element relative to the viewport.

The sticky position means that the element will be positioned sticky, relative to the viewport. The top, left, right, and bottom properties can be used to specify the position of the element relative to the viewport.

The bottom property specifies the y (vertical) coordinate for a positioned element, relative to the bottom of the enclosing object or browser window.

The border property specifies the width and style of the border around an element.

The none of the mentioned option is incorrect because it does not specify the y (vertical) coordinate for a positioned element, relative to the bottom of the enclosing object or browser window.
