Set the transparency of the background image, not the color, it is the image display
This Just like some blogs can change the background image as the theme, after reading it for a long time, I finally figured out that
cannot directly set the transparency of the imageYou need to use< ;div>
<style type="text/css">
.bodystyle{

-moz-opacity:0.5;

position:absolute;
background:url(图像/8.JPG) ;
background-attachment:fixed;
