代码实现导航栏分割线_html/css_WEB-ITnose

无需背景图片就可以实现导航栏分割线，颜色自定，线段虚实自定。

    .nav1{
              width:auto;
              height:50px;
              text-align:center;
              margin:13px auto 0;
            }

            .nav1 a{
              display: inline-block;
     text-decoration:none;
          }
