:read-write CSS 伪类 代表一个元素（例如可输入文本的 input元素）可以被用户编辑。

/* 选择所有可编辑的 <input> 元素 */
/* Firefox 中需要加前缀 */
input:-moz-read-write {
  background-color: #bbf;
}

/* Supported in Blink/WebKit/Edge without a prefix */
input:read-write {
  background-color: #bbf;
}

注意：这个选择器不仅仅选择 {{htmlElement("input")}} 元素，它也会选择所有可以被用户编辑的元素，例如设置了 {{htmlattrxref("contenteditable")}} 属性的  {{htmlelement("p")}} 元素。
