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。

这个问题可能很老了,但它值得更新。 这里有另一种方法:

#yourdiv {
    display: flex;
    width:100%;
    height:100%;
}

其他回答

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.

通常,当父Div的子元素被浮动时,就会出现这个问题。以下是该问题的最新解决方案:

在你的CSS文件中写入下面的类。clearfix和伪选择器

.clearfix:after {
content: "";
display: table;
clear: both;
}

然后,在你的HTML中,添加.clearfix类到你的父Div中。例如:

<div class="clearfix">
    <div></div>
    <div></div>
</div>

它应该一直工作。您可以将类名调用为.group而不是.clearfix,因为这将使代码更具语义性。注意,在双引号“”之间的Content值中不需要添加点甚至空格。另外,overflow: auto;也许可以解决问题,但它会导致其他问题,如显示滚动条,不建议使用。

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。

使用flex

.parent{
    display: flex
}

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