left Attribute | left Property

Sets or retrieves the position of the object relative to the left edge of the next positioned object in the document hierarchy.

Syntax

HTML { left: sPosition }

Scripting object.style.left [ = sPosition ]

HTML	{ left: sPosition }
Scripting	object.style.left [ = sPosition ]

Possible Values

sPosition String that specifies one of the following values:

auto 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, pc, or px) or a relative units designator (em or ex). For more information about the supported length units, see CSS Length Units.

percentage Integer, followed by a %. The value is a percentage of the width of the parent object.

This property is read/write with a default value of auto; the cascading style sheets (CSS) attribute is not inherited.
Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see Dynamic Properties.

Remarks

You should use the left attribute only when the position attribute is set; otherwise, the value of the left attribute is ignored.

Because the value of the left property is a string, you cannot use the property in script to calculate the position of the object in the document; instead, you should use the pixelLeft property or the posLeft property.

For more information about how to access the dimension and location of objects on the page through the DHTML object model, see Measuring Element Dimension and Location.

Example

The following examples use the left attribute and the left property to change the position of the object.
