1、背景
background-color：背景色
<div style="width:50px; height:50px; background-color:#F00;">
background-image:背景图
<body> ??<div style="width:100px; height:100px; background-color:#6C3; background-image:url(lx1.png);"> ???gyvgvgv ????</div></body>
background-repeat：no-repeat不平铺；repeat平铺；repeat-x横向平铺；repeat-y纵向平铺
<body> ???<div style="width:100px; height:100px; background-color:#6C3; background-image:url(lx1.png); background-repeat:no-repeat"> ???<!--no-repeat不平铺；repeat平铺；repeat-x横向平铺；repeat-y纵向平铺--> ????</div></body>
background-position：调整背景图片位置（repeat：no-repeat）；center居中；
<body> ???<div style="width:100px; height:100px; background-color:#6C3; background-image:url(lx1.png); background-repeat:no-repeat; background-position:center"> ????</div></body>
background-position当设置左右必须有上下位置才起作用
<body> ???<div style="width:100px; height:100px; background-color:#6C3; background-image:url(lx1.png); background-repeat:no-repeat; background-position:left 10px top 10px"> ????</div></body>
