}Description
Internet Explorer for Windows
versions 5.5 and above support the non-standard property zoom, which sets the
magnification scale of an element. There’s no CSS3 equivalent to this
property (as yet).
The zoom property isn’t
inherited, but it will affect the children of the element to which it is
applied, which will be magnified along with the parent. The content
surrounding an element that has zoom applied will
reflow to account for the resizing that will occur when
zoom is set to a value other than
normal.
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 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).
