Div高度100%，并扩展到适合内容

I have a div element on my page with its height set to 100%. The height of the body is also set to 100%. The inner div has a background and all that and is different from the body background. This works for making the div height 100% of the browser screen height, but the problem is I have content inside that div that extends vertically beyond the browser screen height. When I scroll down, the div ends at the point at which you had to begin scrolling the page, but the content overflows beyond that. How do I make the div always go all the way to the bottom to fit the inner content?

这是我的CSS的简化:

body {
    height:100%;
    background:red;
}

#some_div {
    height:100%;
    background:black;
}

一旦我滚动页面，黑色就结束了，内容就会流向红色背景。不管我在#some_div上设置的位置是相对的还是绝对的，问题都发生了。#some_div中的内容大多是绝对定位的，并且它是从数据库动态生成的，因此无法预先知道它的高度。

好吧，我试过这样的方法:

身体(正常)

#MainDiv { 
  /* where all the content goes */
  display: table;
  overflow-y: auto;
}

这不是正确的写法，但如果你让主div显示为表格，它会展开，然后我实现滚动条。

Old question, but in my case i found using position:fixed solved it for me. My situation might have been a little different though. I had an overlayed semi transparent div with a loading animation in it that I needed displayed while the page was loading. So using height:auto / 100% or min-height: 100% both filled the window but not the off-screen area. Using position:fixed made this overlay scroll with the user, so it always covered the visible area and kept my preloading animation centred on the screen.

我不完全确定我是否理解了这个问题，因为这是一个相当直截了当的答案，但是……：）

您是否尝试过将容器的溢出属性设置为可见或自动?

#some_div {
    height:100%;
    background:black; 
    overflow: visible;
    }

添加这些内容可以将黑色容器推到动态容器所需的大小。比起auto，我更喜欢可见，因为auto似乎自带滚动条。

在我的情况下，它只适用于:

height: auto;

你不需要放display: block。

#some_div {    
  height: fit-content;
}
