##Implementation Principle
In the html code, The middle part must first be placed at the front part of the container, then left and right 1. Set float:left, position:relative for all three (because relative positioning will be used later)
2.Middle set width :100% occupies a row
3. At this time, the middle occupies a row, so you need to drag the left to the far left of the row where the middle is located, and use margin-left:-100%
4. At this time, the left is pulled back The leftmost side of the row where middle is located, but it will cover the left end of the middle content. To pull out the middle content, add padding: 0 210px
5. The middle content is pulled out, but the left is also pulled out. So to restore, use relative positioning left:-210px
6. In the same way, right should be moved to the far right of the row where middle is located, use margin-left:-210px, right:-210px
