ul.nav

 margin:0; background-position:center;  background-image: url(../images/nav_bg.gif);font-family: "Century Gothic"; height:40px; padding-left:30px;
}

background-position: center top;background-repeat: no-repeat;text-decoration:none !important;vertical-align:middle;

水平和垂直位置由background-position属性控制。第一个数字定义水平位置,第二个数字定义垂直位置。

单词可以用于横向,例如leftrightcenter,对于纵向,它是topbottomcenter 。绝对位置也可以使用,例如像素 ems ,以及百分比

例如:

background-position: right top; /* positioned to the right and the top */
background-position: 100% 0; /* positioned 100% to the right and zero from the top (the same as above) */
background-position: 50px 200px; /* positioned 50px from the left and 100px from the top */

您为背景位置指定了一个值,这意味着它用于水平定位,垂直定位设置为50%。您应指定两个值来控制两个位置。例如:

background-position: left center;
