<integer>
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The <integer> CSS data type is a special type of <number> that represents a positive or negative whole number. Integers can be used in numerous CSS properties and descriptors, such as the column-count, counter-increment, grid-column, grid-row, and z-index properties and the range descriptor.
Syntax
The <integer> data type consists of one or several decimal digits, 0 through 9 inclusive, optionally preceded by a single + or - sign. There is no unit associated with integers.
Note:
There is no official range of valid <integer> values, and the specifications do not specify a range.
Interpolation
When animated, values of the <integer> data type are interpolated using discrete, whole steps. The calculation is done as if they were real, floating-point numbers; the discrete value is obtained using the floor function. The speed of the interpolation is determined by the easing function associated with the animation.
Examples
