IE6下有些bug需要做下兼容
1. IE6的奇偶bug
如果定位外框高度或是宽度为奇数，则IE6下，绝对定位元素的低定位和右定位会有1像素的误差。所以，尽量保证外框的高度或宽度为偶数值。
2. IE6的空p莫名高度bug
IE6下，空p会有莫名的高度，也就是说height:0;不顶用，此时形成的尖角的实际占高于其他浏览器是有差异的。可使用font-size:0; + overflow:hidden;修复此问题。
3. IE6不支持实线边框透明transparent属性
IE6不支持实线边框透明transparent属性，当某边框设置为transparent属性，且有宽度的话，那么透明会以默认的黑色显示的。解决方法有两个，一是将需要隐藏的颜色设置为背景色，这样与透明效果一样，此法有局限性，在复杂“边框法”应用下是行不通的；二是可以使用dashed代替solid，可以实现IE6下边框transparent透明。
