日記背景圖語法－雙層圖＋透明動圖
不固定雙層背景圖+透明動圖語法<style type="text/css">
body{background:url(下層透明動圖) fixed;}
html{background:url(下圖) center;}
#header {background: url(上圖刊頭) center no-repeat;height:刊頭高度px;}</style>
若不想用動圖 (下層透明動圖) 欄位空下即可() 
下列是另外一款語法：(透明動圖在上方)<style type="text/css">
body {background : url() fixed;}
html{background: url(大背景圖) #000000 no-repeat;background-position:50% 25px;}
#header {height:350px;background:url(上層透明動圖);} </style>
