一、使用css，参考国外的一个解决方法：

How to use the CSS Sticky Footer on your website
Add the following lines of CSS to your stylesheet. The negative value for the margin in .wrapper is the same number as the height of .footer and .push. The negative margin should always equal to the full height of the footer (including any padding or borders you may add).
* {
margin: 0;
}
html, body {
height: 100%;
}
.wrapper {
min-height: 100%;
height: auto !important;
height: 100%;
margin: 0 auto -4em;
}
.footer, .push {
height: 4em;
}
Follow this HTML structure. No content can be outside of the .wrapper and .footer div tags unless it is absolutely positioned with CSS. There should also be no content inside the .push div as it is a hidden element that "pushes" down the footer so it doesn't overlap anything.
