需要帮助将Divs放置在彼此顶部，并将最后一个放在底部

Question

我正在尝试构建一个页面，我希望最后一个div处于底部，但它的顶部(第二位于最后一个(可以在调整大小或当元素不合适时。这是指向我的JSFIDDLE(https://jsfiddle.net/tgz98s6w/(的链接，您可以看到有时与最后一个div重叠的第二个链接，有时我想避免使用。我尝试设置：

#windowsStoreBox {
    position: absolute;
    bottom: 0;
}

，但似乎不起作用。谢谢你

Answer 1

我不确定我是否已经误解了，但是您是因为您使用的是修复程序，并且绝对将它们排除在正常文档流中。

因此，您可以轻松限制#servicesBox的高度。为了防止它接触底部。
