Definition and Usage

The top property affects the vertical position of a positioned element. This property has no effect on non-positioned elements.

If position: absolute; or position: fixed; - the top property sets the top edge of an element to a unit above/below the top edge of its nearest positioned ancestor.
If position: relative; - the top property makes the element's top edge to move above/below its normal position.
If position: sticky; - the top property behaves like its position is relative when the element is inside the viewport, and like its position is fixed when it is outside.
If position: static; - the top property has no effect.
