CSS Position


position: relative lets you position an element relative to its default static position on the web page.

Offset properties are used to move the element away from its default static position. They are top, bottom, left and right.


absolute position makes all other elements on the page ignore the element for which it is set. The element itself will be positioned relative to its closest positioned parent element. Offset properties can be used to determine the final position.


This position is used to fix an element to a specific position on the page. User scrolling will not make it disappear. It is often used to fix a title or navigation bar on a web page.

When fixed, an element is removed from the flow of the HTML document. To fix this, the section covered by the fixed element should be set to relative and offsetted by the number of pixel used by the fixed element.

header {
  position: fixed;
  width: 100%;

.jumbotron {
  text-align: center;
  width: 100%;
  position: relative;

The z-index property may come handy to keep the fixed element above all the other element. z-index property does not work on static elements. When not set, an element as a z-index value of 0.


The sticky value keeps an element in the document flow as the user scrolls but sticks to a specified position as the page is scrolled further.
