bottom property

Sets or retrieves the bottom position of the object in relation to the bottom of the next positioned object in the document hierarchy.

Syntax

bottom: length | percentage | auto

Property values

auto: Default. Default position, according to the regular HTML layout of the page.
length: Floating-point number, followed by an absolute units designator (cm, mm, in, pt, or pc) or a relative units designator (em, ex, or px). For more information about the supported length units, see CSS Values and Units Reference.
percentage: Integer, followed by a percent sign (%). The value is a percentage of the height of the parent object.

Standards information

CSS 2.1, Section 9.3.2

Remarks

The bottom attribute should be used only when the position attribute is set; otherwise, the value of the bottom attribute is ignored.

Because the value of the bottom property is a string, the property cannot be used in script to calculate the position of the object in the document; instead, the pixelBottom property or the posBottom property should be used.

For more information about how to access the dimension and location of objects on the page through the Dynamic HTML (DHTML) object model, see Measuring Element Dimension and Location with CSSOM in Internet Explorer 9.

Examples

The following example uses the bottom property to change the position of the red div. In the example below, there are four div elements with absolute positioning. The red div is positioned at 10% from the bottom.
