Examples
Positioning elements as static
Use static to position an element according to the normal document flow. HTML elements are static by default.
static parentabs child<div class="static p:5x"> <div>static parent</div> <div class="abs left:10px bottom:10px">abs child</div></div>Positioning elements as relative
Use rel to keep an element in the normal document flow while offsetting it relative to itself with top, right, bottom, and left values.
relative parent<div class="rel p:5x top:30px left:20px"> <div>relative parent</div></div>Positioning elements as absolute
Use abs to remove an element from the normal document flow and position it relative to its closest positioned ancestor.
relative parentabs child<div class="rel p:12x"> <div>relative parent</div> <div class="abs left:0 top:0">abs child</div></div>Positioning elements as fixed
Use fixed to remove an element from the normal document flow and position it relative to the viewport.

Use sticky to position an element based on scroll position. It behaves like a relatively positioned element until a given offset is reached, then sticks to that offset.
