CSS dropshadow 没有到达页面底部？

Question

我想在我的主要内容的两侧使用阴影，但它没有到达页面底部。它在结束前将它切断了大约 100 像素。一直想不通为什么。非常感谢任何帮助！

1) Padding is only placed on the top and/or bottom of the div. The elements within this div have padding on their sides. This saves you from any "box model math". Keep in mind, if you add any side padding or border to the div itself, it will be added to the width you define to create the *total* width. You may also choose to remove the padding on the element in the div and place a second div within it with no width and the padding necessary for your design.

Answer 1

您需要删除您的body 和html 高度（100% 仅使用浏览器高度）并在关闭您的container div 之前放置一个清除 div。

清除 div：<div style="clear: both;"></div>
