CSS Positioning Overview

The only thing I want you to learn from this post is how different positioning values behave, the article is meant to be technical-agnostic. Enjoy!
#1 AUTO (STATIC)
A position auto (static) element follows the document flow (from top to bottom).

#2 RELATIVE
A position relative element is NOT removed from the document flow and can move around it’s original position.
A position relative element can partially overlap nearby elements.

#3 ABSOLUTE
A position absolute element is removed from the document flow and can move freely inside it’s relative-positioned parent.

#4 FIXED
A position fixed element is removed from the document flow and can move freely within the boundaries of the viewport.
