The html, body, and container in the page must all meet height:100%, so that it can occupy the entire screen (page). The footer uses relative positioning bottom:0 and is fixed at the bottom of the page. The main page container must set a padding-bottom that is greater than or equal to the height of the footer. The purpose is to The height of the footer is calculated in the page container, so that the footer will always be fixed at the bottom of the page.

Implementation:

HTML

 
Header Section
 
 
Left Sidebar
 
Main content
 
Right sidebar
 
 
Footer Section
 

The only thing to note here is that the footer container is included in the container container.

CSS

html,body { margin: 0; padding:0; height: 100%; } #container { min-height:100%; height: auto !important; height: 100%; /*IE6不识别min-height*/ position: relative; } #header { background: #ff0; padding: 10px; } #page { width: 960px; margin: 0 auto; padding-bottom: 60px;/*等于footer的高度*/ } #footer { position: absolute; bottom: 0; width: 100%; height: 60px;/*脚部的高度*/ background: #6cf; clear:both; } /*=======主体内容部分省略=======*/

From the css code, we see that the page body page has a padding-bottom set, and it is consistent with the height of the footer. Margin-bottom cannot be used here instead of padding-bottom.

This solution has a disadvantage: footer must have a fixed height, and page must set a padding-bottom greater than or equal to this height. If the footer is not of fixed height, or the footer needs to be adapted, then this solution is not suitable.
