下面的方法对我很有效:

html { height: 100vh; }

body {
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  width: 100vw;
}

/* this is the container you want to take the visible viewport  */
/* make sure this is top-level in body */
#your-app-container {
  height: 100%;
}

body将采用可见视口高度，而#your-app-container with height: 100%将使容器采用可见视口高度。

下面是我在React应用程序中使用的一个方法。

iPhone 11 Pro和iPhone Pro Max - 120px

iPhone 8 - 80px

max-height: calc(100vh - 120px);

这是一个折衷方案，但相对简单

Brave浏览器在iOS上的表现不同(有bug ?)它根据显示/隐藏地址栏动态改变视口高度。这有点烦人，因为它改变页面的布局取决于vw/vh单位。

Chrome和Safari都没问题。

不幸的是，这是故意的……

这是一个众所周知的问题(至少在safari mobile中)，这是故意的，因为它可以防止其他问题。Benjamin Poulain回复了一个webkit漏洞:

This is completely intentional. It took quite a bit of work on our part to achieve this effect. :) The base problem is this: the visible area changes dynamically as you scroll. If we update the CSS viewport height accordingly, we need to update the layout during the scroll. Not only that looks like shit, but doing that at 60 FPS is practically impossible in most pages (60 FPS is the baseline framerate on iOS). It is hard to show you the “looks like shit” part, but imagine as you scroll, the contents moves and what you want on screen is continuously shifting. Dynamically updating the height was not working, we had a few choices: drop viewport units on iOS, match the document size like before iOS 8, use the small view size, use the large view size. From the data we had, using the larger view size was the best compromise. Most website using viewport units were looking great most of the time.

没有修复计划

在这一点上，除了避免在移动设备上使用视口高度之外，你没有什么可以做的。Chrome在2016年也变成了这样:

尝试html, body {height: 100%}在移动设备上达到100vh的效果。

找到这个答案的人正在与移动视图上向下/向上滚动的固定位置的元素的连接跳跃问题作斗争，根元素需要在底部而不是顶部指定属性，并且应该在px中给出一个字段值。这就解决了问题

改变: 元素{ 位置:固定; 上图:90年vh; 左:90 vh; 转换:翻译(-95%，-95%); ｝

:

元素{ 位置:固定; 底部:90 px;/*这是更改*/ 左:90 vh; 转换:翻译(-95%，-95%); }
