One of the main uses for zoom has been to ensure that an element has a layout. It??™s
commonly used with a value of 1.0 (normal), so that no other changes are evident
on the page. Refer to The Internet Explorer hasLayout Property (p. 158) for a longer
discussion of the usage that the zoom property can be put to when debugging CSS
issues in Internet Explorer.
Value
The value normal is the default, and produces no magnification.
Number values are specified as floating-point numbers that represent the
magnification scale where 1.0 is equivalent to normal.
Percentage values represent a percentage of the magnification scale where 100% is
equal to normal (note that decimals of percentages are ignored).
