The CSSPosition (positioning) position attribute specifies the positioning type of the element. The five values of the position attribute: the top, bottom, left, and right attributes that the staticrelativefixedabsolutesticky element can use.

Position property browser support

IE Firefox Chrome Safari Opera

All major browsers support the position attribute.

Note: no version of InternetExplorer (including IE8) supports the attribute value "inherit".

Definition and usage of position attribute

The position attribute specifies the positioning type of the element.

Description

This attribute defines the positioning mechanism used to establish the layout of the element. Any element can be located, but an absolute or fixed element generates a block-level box, regardless of the type of the element itself. The relative positioning element is offset from its default position in the normal flow.

Default value: static

Inheritance: no

Version: CSS2

JavaScript syntax: object.style.position= "absolute"

Possible value

Value description

Absolute

The element that generates absolute positioning is positioned relative to the first parent element other than static positioning.

The location of the element is specified by the "left", "top", "right", and "bottom" attributes.

Fixed

Generates an absolutely positioned element, positioned relative to the browser window.

The location of the element is specified by the "left", "top", "right", and "bottom" attributes.

Relative

The relative positioning element is generated and positioned relative to its normal position.

Therefore, "left:20" adds 20 pixels to the LEFT position of the element.

Static default value. Without positioning, the element appears in the normal flow (ignoring the top,bottom,left,right or z-index declaration).

Inherit states that the value of the position attribute should be inherited from the parent element.
