inheritance: No compatibility: IE basic Syntax zoom:normal | Number syntax value NORMAL: Default value. Use the actual size of the object number: percent | Unsigned floating-point real number. A floating-point real value of 1.0 or a percentage of 100% is equivalent to the normal value of this property. Use the description to set or retrieve the object's zoom ratio. Setting or changing this property value of an object that has been presented will cause the content of the wrapping object to flow again. Although this property is not inheritable, it affects all of the object's child objects (children). This effect is much like the change caused by the background and filter properties. This property is read-only for Currentstyle objects. Readable and writable for other objects.
Zoom:1 is the same size as the original.
What does "zoom:1" mean in CSS?
