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。
