<number>

The <number> CSS data type represents a number, being either an integer or a number with a fractional component.

Syntax

The syntax of <number> extends the syntax of <integer>. A fractional value is represented by a . followed by one or more decimal digits, and may be appended to an integer. There is no unit associated with numbers.

Interpolation

When animated, values of the <number> CSS data type are interpolated as real, floating-point numbers. The speed of the interpolation is determined by the timing function associated with the animation.
