Step-by-step explanation:
Position absolute is a CSS property that allows you to control the positioning of an element relative to its nearest positioned ancestor or the containing block. When an element is set to position: absolute, it is taken out of the normal document flow, which means it does not affect the position of other elements. It is positioned based on its top, right, bottom, and left properties, which you can specify to determine its exact position on the page.
