导航下面有一细白线，求指点。虽然通过margin_bottom=-3px;可以纠正。但我的问题出在哪里呢？
回复讨论(解决方案)
设置：#nave li{display:inline;} #nave li a{display:block;}试试看
设置：#nave li{display:inline;} #nave li a{display:block;}试试看 搞定了，问题不是 a标签，我调试了很久发现只要设置一个img{margin-bttom:-3px}就正常了
ie6版本 的 ul列表框 有个bug，会在 li上下添加额外的空间，所以一般的修正办法都是 设置 li｛第四play：inline｝，而其中的锚元素 ，一半设置成 block即可了
