CSS Layout - The position Property


The position property specifies the type of positioning method used for an element .It can also place an element behind another, and specify what should happen when an element's content is too big.


The position Property

The position property specifies the type of positioning method used for an element.

There are four different position values:

  • static
  • relative
  • fixed
  • absolute

Elements are then positioned using the top, bottom, left, and right properties .


position: static;

HTML elements are positioned static by default.

Static positioned elements are not affected by the top, bottom, left, and right properties.

A static positioned element is always positioned according to the normal flow of the page.

This <div> element has position: static;

Here is the CSS that is used:

Example

div.static {
    position: static;
    border: 3px solid blue;
}

position: relative;

An element with position: relative; is positioned relative to its normal position.

The properties top, right, bottom, and left can be used to specify .

This <div> element has position: relative;

Here is the CSS that is used:

Example

div.relative {
    position: relative;
    left: 30px;
    border: 3px solid green;
}

position: fixed;

An element with position: fixed; is positioned relative to the viewport, which means it always stays in the same place even if the page is scrolled. The top, right, bottom, and left properties are used to position the element.

A fixed element does not leave a gap in the page where it would normally have been located.

Notice the fixed element in the lower-right corner of the page. Here is the CSS that is used:

Example

div.fixed {
    position: fixed;
    bottom: 0;
    right: 0;
    width: 300px;
    border: 3px solid #73AD21;
}

This <div> element has position: fixed;

position: absolute;

An element with position: absolute; is positioned relative to the nearest positioned ancestor (instead of positioned relative to the viewport, like fixed).

However; if an absolute positioned element has no positioned ancestors, it uses the document body, and moves along with page scrolling.

Note: A "positioned" element is one whose position is anything except static.

Here is a simple example:

This <div> element has position: relative;
This <div> element has position: absolute;

Here is the CSS that is used:

Example

div.relative {
    position: relative;
    width: 300px;
    height: 150px;
    border: 3px solid blue;
}

div.absolute {
    position: absolute;
    top: 80px;
    right: 0;
    width: 200px;
    height: 100px;
    border: 3px solid green;
}
