所以当它显示在我的网站http://scott.ewarena.com/blog上时它显得非常好，但是当在移动设备上观看时，在视频之前的顶部栏下面顶部有一个间隙，不应该在那里。< / p>
我无法找出问题所在，我已经尝试了两天。
抱歉，我的代码非常笨重。我是新手，并意识到需要清理一下。
任何帮助都将受到青睐！
谢谢！ 斯科特
答案 0 :(得分：1)
在Chrome开发工具中查看了您的代码后，我注意到您在样式表中定义了以下内容：
.video-container video {
position: absolute;
z-index: 0;
bottom: 0;
}
如果删除bottom: 0;，则不会出现此问题！
基本上，您强制将视频置于其容器中最底层的位置，当视口是智能手机大小时，会产生间隙。
