html - 如何在没有垂直滚动的情况下指定屏幕的全高？
问题描述
我希望橙色和蓝色区域到屏幕的末尾或屏幕的全尺寸减去导航栏的高度。一旦我使用vh-100它，它就具有完整的高度，但它会创建一个我不想要的垂直滚动条。所以我想要屏幕的全高或没有滚动条的总高度。我怎么做？Bootstrap 中是否有任何东西可以vh-100 - height of the navbar让一切都适合（但导航栏没有“真实”高度。所以我没有定义导航栏的高度）？或者我怎么能说它应该占据整个高度而不创建垂直滚动条？

解决方案
一种方法是使用高度：设置底部的高度等于视口高度减去导航栏的高度（56px 或 3.5rem）calc(100vh – 3.5rem)。row
或者我添加到您的代码中的另一个选项是使用 flex。
Calc 适用于所有现代浏览器，以及 IE9 及更高版本，而 flex 适用于所有现代浏览器，以及 IE11。
