:in-range
:in-range
该:in-rangeCSS伪类匹配<input>元素且要求<input>元素所包含的值位于由min和max属性所指定的范围限制内。
/* Selects any <input>, but only when it has a range */
/* specified, and its value is inside that range */
input:in-range {
background-color: rgba(0, 255, 0, 0.25
}
注意：这个伪类仅适用于具有范围限制的元素。在没有这种限制的情况下，元素既不能在“范围内”，也不能在“范围之外”。
