      背景(相關css教程
      語法: background: <值>
      允許值: <背景顏色> || <背景圖象> || <背景重復> || <背景附件> || <背景位置>
      初始值: 未定義
      適用于: 所有對象
      向下兼容:
        背景屬性是一個更明確的背景—關系屬性的略寫。以下是一些背景的聲明:
      BODY       { background: white url(http://www.htmlhelp.com/foo.gif) }
      BLOCKQUOTE { background: #7fffd4 }
      P          { background: url(../backgrounds/pawn.png) #f0f8ff fixed }
      TABLE      { background: #0c0 url(leaves.jpg) no-repeat bottom right }
        當一個值未被指定時,將接受其初始值。例如,在上述的前三條規則,背景位置屬性將被設置為0% 0%
      為了避免與用戶的樣式表之間的沖突,背景和顏色應該一起被指定。
