:out-of-range

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.

:out-of-range CSS 伪类表示一个 <input> 元素,其当前值处于属性 minmax 限定的范围外。

尝试一下

这个伪类很有用,可以给用户提供一个视觉提示,让他们知道字段的当前值是否超出了允许的范围。

备注: 该伪类仅适用于具有(并可以接受)范围限制的元素。如果没有这样的限制,元素值就无所谓“in-range”和“out-of-range”。

语法

css
:out-of-range {
  /* ... */
}

        name="value1"
        type="number"
        placeholder="1 to 10"

        max="10"
