-ms-zoom property

Sets or retrieves the magnification scale of the object.

Syntax

-ms-zoom: normal number percentage

Property 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.

CSS information

Applies To	All elements
Media	visual
Inherited	no
Initial Value

Standards information

There are no standards that apply here.

Remarks

Windows Internet Explorer 8. The -ms-zoom attribute is an extension to CSS, and can be used as a synonym for zoom in IE8 Standards mode.

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

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

Examples

The following examples use the -ms-zoom attribute and the -ms-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 -ms-zoom attribute to one-tenth of normal.


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

This example uses inline scripting to set the -ms-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'">

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