Question

无法弄清楚我所有其他移动设备媒体查询的错误是什么，只是我的最后一个验证，我似乎无法在任何地方找到答案。我已经坚持了一段时间。不知道如何修复它，这是我第一次使用媒体查询，我使用1140网格和html5任何想法如何让它来验证。

Answer 1

你错过了结尾括号}：

之后

 @media handheld, only screen and (max-width: 767px) {

只需支架：

   .footer h3{ 
       font-size:.875em;
    }
 } /* here. */

    @media handheld, only screen and (max-width: 320px) {

css不会验证继续获得Parse Error @media掌上电脑，只有屏幕和（max-width：320px）错误
