The <integer>
CSS data type is a special type of <number>
that represents a whole number, whether positive or negative. Integers can be used in numerous CSS properties, such as column-count
, counter-increment
, grid-column
, grid-row
, and z-index
.
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. Opera 12.1 supports values up to 215-1, IE up to 220-1, and other browsers even higher. During the CSS3 Values cycle there was a lot of discussion about setting a minimum range to support: the latest decision, in April 2012 during the LC phase, was [-227-1; 227-1], but other values like 224-1 and 230-1 were also proposed. However, the latest spec doesn't specify a range anymore.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 timing function associated with the animation.
