html - 什么是粘性页脚？

Question

这个问题完全是菜鸟问题，但我无法区分普通页脚和粘性页脚。

Answer 1

取自CSS tricks :

The purpose of a sticky footer is that it "sticks" to the bottom of the browser window. But not always, if there is enough content on the page to push the footer lower, it still does that. But if the content on the page is short, a sticky footer will still hang to the bottom of the browser window.

以下是粘性页脚的清晰概念:https://css-tricks.com/couple-takes-sticky-footer/和 http://css-tricks.com/sticky-footer/
