CSS3选择器 :read-only选择器
“:read-only”伪类选择器用来指定处于只读状态元素的样式。简单点理解就是,元素中设置了“readonly=’readonly’”
例如:设置textarea的只读样式。
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>属性选择器</title> <style> form { width: 300px; padding: 10px; border: 1px solid #ccc; margin: 50px auto; } form > div { margin-bottom: 10px; } input[type="text"]{ border: 1px solid orange; padding: 5px; background: #fff; border-radius: 5px; } input[type="text"]:-moz-read-only{ border-color: #ccc; } input[type="text"]:read-only{ border-color: #ccc; } textarea:-moz-read-only{ border: 1px solid red; height: 50px; resize: none; background: #eee; } textarea:read-only { border: 1px solid red; height: 50px; resize: none; background: #eee; } </style> </head> <body> <form action="#"> <div> <label for="name">姓名:</label> <input type="text" name="name" id="name" placeholder="大漠" /> </div> <div> <label for="address">地址:</label> <input type="text" name="address" id="address" placeholder="中国上海" readonly="readonly" /> </div> <div> <label for="comment">评论:</label> <textarea name="comment" id="" cols="30" rows="10" readonly="readonly"></textarea> </div> </form> </body> </html>
