In this article, you’ll learn how to use CSS position: relative and position: absolute through ample amounts of demos, and learning aids.. CSS position is sometimes considered an advanced topic because it can do things that are somewhat unexpected. Both “relative” and “absolute” positioning are really relative, just with different framework. “Absolute” positioning is relative to the position of another, enclosing element. “Relative” positioning is relative to the position that the element itself would have without positioning. 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 with a -webkit- prefix. A fixed position element is positioned relative to the viewport, or the browser window itself.

In contrast, an element that is absolutely positioned is taken out of the flow; thus, other elements are positioned as if it did not exist. The absolutely positioned element is positioned relative to its nearest positioned ancestor i.
If a positioned ancestor doesn't exist, it is positioned relative to the ICB initial containing block — see also the W3C definition , which is the containing block of the document's root element.
Fixed positioning is similar to absolute positioning, with the exception that the element's containing block is the initial containing block established by the viewport , unless any ancestor has transform , perspective , or filter property set to something other than none see CSS Transforms Spec , which then causes that ancestor to take the place of the elements containing block.
