بنية CSS

position: static|absolute|fixed|relative|sticky|initial|inherit;

قيم الملكية

Value Description Play it
static Default value. Elements render in order, as they appear in the document flow
absolute The element is positioned relative to its first positioned (not static) ancestor element
fixed The element is positioned relative to the browser window
relative The element is positioned relative to its normal position, so "left:20px" adds 20 pixels to the element's LEFT position
sticky The element is positioned based on the user's scroll position

A sticky element toggles between relative and fixed, depending on the scroll position. It is positioned relative until a given offset position is met in the viewport - then it "sticks" in place (like position:fixed).

Note: Not supported in IE/Edge 15 or earlier. Supported in Safari from version 6.1 with a -webkit- prefix.
initial Sets this property to its default value. Read about initial
inherit Inherits this property from its parent element. Read about inherit
