运行的时候，显示页面有错误，而且只出现一遍，鼠标到头再返回去就不会出现效果了
错误1：id值为NewsTop_tit的div标签没有正确关闭；
错误2：上面这个元素中的p元素数量与id值为NewsTop_cnt的div元素中的span子元素数量不匹配。
标签没有问题吧
错误2：上面这个元素中的p元素数量与id值为NewsTop_cnt的div元素中的span子元素数量不匹配。

Error 1: The div tag with the id value NewsTop_tit is not closed correctly;
Error 2: The number of p elements in the above element does not match the number of span sub-elements in the div element with the id value NewsTop_cnt.

There is another question, I need to ask, how to implement it...
In Henan and Hebei, I use two DIVs. You mentioned margin-top and padding-top. Which one should I put it in?
#NewsTop_tit p, #NewsTop_two p { margin-bottom:0;}To be honest, the code you posted is really bad and it is very difficult to adjust. Look at the margin-top and margin-bottom of the box model #NewsTop_tit p, #NewsTop_two p element The values are all 10px, but after forcibly changing the margin value like above, the effect is different in IE and other browsers.
CSS code
#NewsTop_tit p, #NewsTop_two p {
margin-bottom:0;
}
I tried this and it works, thank you.
