响应式网站的内容低于固定标题

Question

I have the following simple HTML and CSS code: 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>

First of all, sorry for the long random content but it is the only way to reproduce my issue on your local computer. 首先，对于长期的随机内容表示抱歉，但这是在本地计算机上重现我的问题的唯一方法。

The code above displays a fixed a header and a content of a website. 上面的代码显示了固定的网站标题和内容。
You can also find all the code in the jsfiddle here . 您还可以找到的jsfiddle所有的代码在这里。

All this works fine so far. 到目前为止，所有这些工作正常。

The idea of the above code is to be responsive so when I minimize the screen the header and content adjust automatically. 上面代码的思想是响应，因此当我最小化屏幕时，标题和内容会自动调整。 In general, this seems to work. 通常，这似乎可行。
However, for the property margin-top:10%; 但是，对于财产margin-top:10%; I have the problem that the content goes below the fixed header if I minimize the screen size. 我有一个问题，如果我最小化屏幕尺寸，内容将低于fixed header 。

Is there a way to make sure that there is always a margin between the header and the content no matter if I access the website from mobile or from the web? 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

You can do this, if you move all of the rest of your site content into the .content div (as you have done). 如果将所有其余网站内容都移到.content div中，则可以执行此操作。

Make these changes to your .content css 对您的.content CSS进行这些更改

Replace margin-top with top: 20% margin-top替换margin-top top: 20%
Add position: absolute 添加position: absolute
Add height: 80% height: 80%
Add overflow: auto 添加overflow: auto

This puts all your content into a scrollable container that fills the rest of the height. 这会将您的所有内容放入一个可滚动的容器中，该容器将填充其余高度。 Which leaves the margin below your menu 这使菜单下面的边距

But honestly, I wouldn't suggest this from a UX perspective 但老实说，我不会从用户体验的角度提出建议

Answer 2

I further researched the issue and the best approach I could find is to change the margin-top property of the content element to margin-top: 20vh; 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

The cause of the problem you're seeing is that you're using percentage values. 您看到的问题的原因是您使用的是百分比值。 These values are based on on the parent element. 这些值基于父元素。 In your case the parent element is the <body> tag which defaults to the size of the viewport. 在您的情况下，父元素是<body>标签，默认为视口的大小。

10% height on a 4k screen is very different from 10% on a mobile screen. 4k屏幕上的10％高度与移动屏幕上的10％高度差异很大。 Consider using different values for your height and margin-top properties. 考虑为您的height和margin-top属性使用不同的值。 You can either use px values of em values 您可以使用em值的px值

Something like this: 像这样：

 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 { margin-top: 4em; background-color: red; }
