:read-only

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2020.

:read-only CSS 伪类 表示元素不可被用户编辑的状态(如锁定的文本输入框)。

css
/* Selects any <input> element that is read-only */
/* Supported in Firefox with a prefix */
input:-moz-read-only {
  background-color: #ccc;
}

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

备注: 这个选择器不只是选择具有 readonly 属性的<input> 元素,它也会选择所有的不能被用户编辑的元素。
