The <integer> CSS data type is a special type of {{cssxref("number")}} that represents a whole number, whether positive or negative. Integers can be used in numerous CSS properties, such as {{cssxref("column-count")}}, {{cssxref("counter-increment")}}, {{cssxref("grid-column")}}, {{cssxref("grid-row")}}, and {{cssxref("z-index")}}.
+ The <integer> css数据类型是一种特殊的<number>类型，它表示一个整数，无论是正数还是负数。整数可以用于许多css属性，例如{{cssxref("column-count")}}, {{cssxref("counter-increment")}}, {{cssxref("grid-column")}}, {{cssxref("grid-row")}}, and {{cssxref("z-index")}}.

+ +

语法

+ +

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.
+ <integer>数据类型由一个或多个十进制数字组成，包括0到9，可以选择前面加一个+或-号。没有与整数关联的单位。

+ +
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.
+注意：没有有效的<integer>值的正式范围。Opera12.1支持高达215-1的值，IE高达220-1的值，其他浏览器支持更高的值。在CSS3值周期中，有很多关于设置最小支持范围的讨论：2012年4月在LC阶段的最新决定是[-227-1; 227-1],，但也提出了224-1 and 230等其他值。但是，最新的规范不再指定范围。
+ +

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.
+ 设置动画时，<integer>数据类型的值将使用离散的完整步骤进行插值。计算过程就像是实数，浮点数一样；离散值是使用floor函数得到的。插值的速度由与动画相关联的定时函数确定。

++---12      Only one leading +/- is allowed.
+ten         Letters are not allowed.
+_5          Special characters are not allowed.
+\35         Escaped Unicode characters are not allowed, even if they are an integer (here: 5).
