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。

使用flex

.parent{
    display: flex
}

.fit-parent{
    display: flex;
    flex-grow: 1
}

现代浏览器支持“视口高度”单位。这将把div展开到可用的视口高度。我发现它比其他任何方法都可靠。

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

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.

试试这个:

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

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

IE6及之前版本不支持min-height属性。

我认为问题是，当你告诉主体的高度为100%时，它的背景只能和一个浏览器“视口”(不包括浏览器工具栏、状态栏、菜单栏和窗口边缘的查看区域)的高度一样高。如果内容高于一个视口，它将溢出专门用于背景的高度。

如果你的内容没有填满一整个页面的底部，主体上的min-height属性应该强制背景至少和一个视口一样高，然而，它也应该让它向下生长，以包含更多的内部内容。

以下是在CSS样式中，在主div上应该做的事情

display: block;
overflow: auto;

不要碰高度
