: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。

语法
