http://img1.sycdn.imooc.com//59127fea000176a013620305.jpg

代码如下:

.nav

{

height:40px;

}


.nav_left

{

width:10px;

background:url(../images/nav_left.jpg) no-repeat;

  /*background-image:url(../images/nav_left.jpg);

background-repeat:no-repeat;*/

float:left;

}


.nav_mid

{

width:980px;

background:url(../images/nav_bd.jpg) repeat-x;

float:left;

}


.nav_right

{

width:10px;

background:url(../images/nav_right.jpg) no-repeat;

float:left;

}

检查了一中午的代码,终于知道错误在哪里了,写错了一个英语字母,多么痛的领悟!要平铺的图片,nav_bg.jpg写成nav_bd.jpg了......

.nav_mid

{

width:980px;

background:url(../images/nav_bd.jpg) repeat-x;

float:left;

}
