您似乎错过了结束</div>标记，这很可能是为什么它会在整个网页上跳转的原因。使用这样的工具来帮助您：http://www.freeformatter.com/html-validator.html

响应式设计很好，但您可能希望更多地关注HTML和CSS。

<center>标签是一个糟糕的黑客。你应该用CSS做到这一点。此外，您还应使用CSS来使用<br> s作为间距。看看填充和边距。

如果你想<center>一个div，那么css替代方法是这样的：

<div class="container">
    <div style="margin:0 auto; width: 800px;">This will be centered </div>
</div>

只是为了让你开始。

这里发生的是容器div填充100％作为标准div应该。子div（带有样式标记的div）将其上下边距设置为0，将其左右边距设置为auto。这里的重要部分是div也有固定的宽度。因此，在这种情况下，div将占用800px，任何剩余的空间将auto在边缘上均匀分布。

你可以谷歌这个，并得到一个更好的解释我确定。
