html - 响应式网站有问题

Question

我在使用手机、平板电脑和台式机/笔记本电脑时遇到检测问题？我想知道我做错了什么。我提供了代码，它并不完整，但我不明白为什么当我将屏幕从移动设备调整为台式机/笔记本电脑显示器时，一切都不合适。我想知道当我返回桌面 View 时如何重置？调整我在网站上显示的图像的大小也有问题。我想根据设备的大小相应地调整大小。我有一个 Logo 图像和一个横幅图像，在这两个图像之上是导航栏，由于导航栏位于灰色背景之上，我在调整大小和使其透明方面也遇到了问题。我怎样才能让它在横幅和标志上透明。我感谢迄今为止获得的所有帮助。我有很大的进步。谢谢你们!

这是html代码:

 /*************************************
TWO COLUMN LAYOUT

 Will target anything larger than average smartphone.
 This is helpful for normal sized tablets, very large smartphones, and very small desktop   windows.
 ***************************************/

 #primary {
width: 50%;
 float: left;
  padding:10px;
 }
 #secondary {
 width: 40%;
 float: right;
 padding:10px;
}

Answer 1

试试这个:

#primary, #secondary {
    dialay:inline-block;
    width:45%;
    padding:.5%;
    margin:.5%;
}

相同的样式适用于两个 div。无需 float 。然后你应该把它们放在一起:

<dig align=center><div id="primary"><div id="secondary"></div>

而且它们应该不错。
