background-repeat属性的定义和用法:
设置或检索对象的背景图像如何铺排填充。
必须先指定background-image属性。
允许提供2个参数，如果提供全部2个参数，第1个用于横向，第二个用于纵向。
如果只提供1个参数，则用于横向和纵向。特殊值repeat-x和repeat-y除外，因为repeat-x相当于repeat no-repeat，repeat-y相当于no-repeat repeat，即其实repeat-x和repeat-y等价于提供了2个参数值。
对应的脚本特性为backgroundRepeat。
语法结构:
background-repeat：repeat-x | repeat-y | [repeat | space | round | no-repeat
取值:
repeat：背景图像在横向和纵向平铺，默认值。
repeat-x：背景图像在横向上平铺。
repeat-y：背景图像在纵向上平铺。
no-repeat：背景图像不平铺。
round：背景图像自动缩放直到适应且填充满整个容器。（CSS3）
space：背景图像以相同的间距平铺且填充满整个容器或某个方向。（CSS3）

2.Firefox4.0-8.0不支持为background-repeat定义2个参数值；不支持CSS3新增参数值round | space。
