Insert the coordinate div to center, and the coordinate div to center

<! Doctype html>
<Meta charset = "UTF-8">
<Meta name = "Author" content = "Hu Chao">
<Title> super Hu </title>
<Style type = "text/css">
Html, body, div {margin: 0; padding: 0}/*, insert a div outside the content Element
And set the div height: 50%; margin-bottom:-(contentheight + padding)/2 ;.

For example, if the content height is 100px and the total padding is 20px, margin-bottom:-60px will squeeze the content down.
The disadvantage is to add meaningless labels, but the advantage is that IE6 is simple and compatible */
