  • <integer>

    <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column-count,counter-increment,grid-column,grid-row,z-index

    插值动画

    设置动画时,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。

    语法

    <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

    实例

    合法整型

    12          Positive integer (without a leading + sign)
    +123        Positive integer (with a leading + sign)
    -456        Negative integer
    0           Zero
    +0          Zero, with a leading +
    -0          Zero, with a leading -
    

    非法整型:

    12.0        This is a , not an , though it represents an integer.
    12.         Decimal points are not allowed.
    +---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).
    \4E94       Non-arabic numerals are not allowed, even when escaped (here: the Japanese 5, 五).
