scale - CSS: Cascading Style Sheets 编辑

The scale CSS property allows you to specify scale transforms individually and independently of the transform property. This maps better to typical user interface usage, and saves having to remember the exact order of transform functions to specify in the transform value.

Syntax

/* Keyword values */
scale: none;

/* Single values */
/* values of more than 1 make the element grow */
scale: 2;
/* values of less than 1 make the element shrink */
scale: 0.5;

/* Two values */
scale: 2 0.5;

/* Three values */
scale: 2 0.5 2;

Values

Single number value

A <number> specifying a scale factor to make the affected element scale by the same factor along both the X and Y axes. Equivalent to a scale() (2D scaling) function with a single value specified.

Two length/percentage values

Two <number>s that specify the X and Y axis scaling values (respectively) of a 2D scale. Equivalent to a scale() (2D scaling) function with two values specified.

Three length/percentage values

Three <number>s that specify the X, Y, and Z axis scaling values (respectively) of a 3D scale. Equivalent to a scale3d() (3D scaling) function.

none

Specifies that no scaling should be applied.
