Question

我有以下简单的HTML和CSS代码：

body {
  margin: 0;
}

.navigation {
  width: 80%;
  height: 15%;
  margin-left: 10%;
  position: fixed;
  top: 0;
  box-sizing: border-box;
  border-style: solid;
  border-width: 1px;
  background-color: yellow;
}

.content {
  width: 80%;
  margin-top: 10%;
  margin-left: 10%;
  box-sizing: border-box;
  border-style: solid;
  border-width: 1px;
  background-color: red;
}

<body>
	
<nav class="navigation">
<div>
Menu
</div>
</nav>
	
<div class="content">
<p>... </p>
<p>... </p>
<p>... </p>
</div>
	
	
</body>

首先，对于长期的随机内容感到抱歉，但这是在本地计算机上重现我的问题的唯一方法。

上面的代码显示固定的网站标题和内容。
您还可以在jsfiddle here中找到所有代码。

到目前为止，所有这些都工作正常。

上面代码的想法是响应，因此当我最小化屏幕时，标题和内容会自动调整。通常，这似乎可行。
但是，对于属性margin-top:10%;，如果最小化屏幕尺寸，则内容将低于fixed header。

无论我是通过移动设备还是通过Web访问网站，是否都可以确保标题和内容之间始终留有空白？

Answer 1

如果将网站的所有其余内容都移到.content div中，就可以执行此操作。

对您的.content CSS进行这些更改

将margin-top替换为top: 20%
添加position: absolute
添加height: 80%
添加overflow: auto

这会将您所有的内容放入一个可滚动的容器中，该容器将填充其余高度。这使空白留在菜单下方

但是，老实说，我不会从用户体验的角度提出建议

Answer 2

我进一步研究了这个问题，发现的最佳方法是将content元素的margin-top属性更改为margin-top: 20vh;

body {
  margin: 0;
}

.navigation {
  width: 80%;
  height: 15%;
  margin-left: 10%;
  position: fixed;
  top: 0;
  box-sizing: border-box;
  border-style: solid;
  border-width: 1px;
  background-color: yellow;
}

.content {
  width: 80%;
  margin-top: 20vh;
  margin-left: 10%;
  box-sizing: border-box;
  border-style: solid;
  border-width: 1px;
  background-color: red;
}

Answer 3

您看到的问题的原因是您使用百分比值。这些值基于父元素。在您的情况下，父元素是<body>标签，默认为视口大小。

4k屏幕上10％的高度与移动屏幕上10％的高度非常不同。考虑为height和margin-top属性使用不同的值。您可以使用px个值中的em个值

类似这样的东西：

body {
  margin: 0;
  display: flex;
  justify-content: center;
}

.navigation,
.content {
  box-sizing: border-box;
  border: 1px solid;
  width: 80%;
}

.content p:first-of-type {
  margin-top: 0;
}

.navigation {
  height: 2em;
  position: fixed;
  background-color: yellow;
}

.content {
