{{CSSRef}}{{Non-standard_header}}

The non-standard zoom CSS property can be used to control the magnification level of an element. {{cssxref("transform-function/scale", "transform: scale()")}} should be used instead of this property, if possible. However, unlike CSS Transforms, zoom affects the layout size of the element.

/* Keyword values */
zoom: normal;
zoom: reset;

/* <percentage> values */
zoom: 50%;
zoom: 200%;

/* <number> values */
zoom: 1.1;
zoom: 0.7;

/* Global values */
zoom: inherit;
zoom: initial;
zoom: unset;

Syntax

Values

normal
Render this element at its normal size.
reset {{non-standard_inline}}

{{cssxref("<percentage>")}}
Zoom factor. 100% is equivalent to normal. Values larger than 100% zoom in. Values smaller than 100% zoom out.
{{cssxref("<number>")}}
Zoom factor. Equivalent to the corresponding percentage (1.0 = 100% = normal). Values larger than 1.0 zoom in. Values smaller than 1.0 zoom out.
