HTML 100vh 不处理 Android 上的浏览​​器工具栏

  • 772

在桌面上，如果我将body或 a设置div为 以便100vh占用所有屏幕空间并让溢出正常运行，则标签的实际高度是浏览器内容窗口的真实可见高度。

相反，在 Android 上（使用 Mozilla Focus 117.0 进行测试），它不会处理浏览器标题，因此页面不完整。

html {
  height: 100%;
}

body {
  min-height: 100%;
}

.content {
  height: 100vh;
}

具体来说，如果用户向下滚动页面时浏览器隐藏工具栏，就会发生这种情况。例如，在我的 apache Web 服务器上运行的完全相同的代码会导致我描述的问题，但无论出于何种原因，如果我在 stackoverflow.com内运行代码片段：

  1. 浏览器不隐藏工具栏
  2. 溢出工作正常

我想可以告诉浏览器保留工具栏（即this），但这对我来说似乎是一个解决方法。

有没有办法在有或没有浏览器工具栏的情况下将可见高度设置为实际可用空间？

这似乎是这个问题的重复，但我不想改变浏览器行为，我只想使用可用空间。

    您可以使用考虑移动地址栏的新视口单元之一。可能较大或动态视口高度（lvh 或 dvh）。

    您可以在这里找到简单的解释： https: //web.dev/viewport-units/

    与往常一样，您应该在使用较新的网络功能之前检查浏览器支持，但在这种情况下，支持已经相当不错： https: //caniuse.com/viewport-unit-variants
