Applies to:
 Sets or retrieves the magnification scale of the object. Microsoft® Internet Explorer 5+ only
Inherited:
 No

Scripting: object.style.zoom [ = vMagnification ]

vMagnification Variant that specifies or receives one of the following values:normal Default. Magnification scale is normal. The object renders normal size.

number Floating-point number that specifies the magnification scale, where 1.0 is normal.
percentage Integer, followed by a %. The value is a percentage of the magnification scale, where 100% is normal.

The property is read/write for all objects with the following exception: currentStyle.

Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. Click here to view the Colour Table

Setting the value of the zoom property on a rendered object causes the content that surrounds the object to reflow.

Even though the zoom property is not inherited, it affects its children. This effect is similar to the transformation caused by the background and filter properties.

Examples

The following examples use the zoom attribute and the zoom property to change the magnification scale of a P element.
This example uses a style rule in an embedded style sheet to set the zoom attribute to one-tenth of normal.

<STYLE>
.clsTeenyWeeny { zoom: 0.10 }
</STYLE>

This example uses inline scripting to set the zoom property to 200% when an onmouseover event occurs. The magnification scale returns to normal when the onmouseout event occurs.

<P onmouseover="this.style.zoom='200%'"
onmouseout="this.style.zoom='normal'">HELP!!!</p>

HELP!!!

This example provides controls that let the user adjust the zoom property.
