overflow-x和overflow-y的冲突问题

[qq_33777786]

overflow-x和overflow-y，如果两个值不同，另一个就会被默认改成auto，我想要的效果是，在一个div里面，上下有滑动框，左右没有，左右方向可以溢出

[_Star_]

overflow:hidden;

[学无止境之问道]

overflow-x:hidden ;overflow-y: auto; 内部div的高河宽都要大于外部

[当作看不见]

overflow-x: hidden;

题主现在解决了吗？同样的需求效果，父级纵向滚动，鼠标移到子级显示绝对定位到右边的孙子级。

overflow-x:hidden ;overflow-y: scroll;

w3c标准就是这么写的

After some serious searching it seems i've found the answer to my question: from: http://www.brunildo.org/test/Overflowxy2.html In Gecko, Safari, Opera, ‘visible’ becomes ‘auto’ also when combined with ‘hidden’ (in other words: ‘visible’ becomes ‘auto’ when combined with anything else different from ‘visible’). Gecko 1.8, Safari 3, Opera 9.5 are pretty consistent among them. also the W3C spec says: The computed values of ‘overflow-x’ and ‘overflow-y’ are the same as their specified values, except that some combinations with ‘visible’ are not possible: if one is specified as ‘visible’ and the other is ‘scroll’ or ‘auto’, then ‘visible’ is set to ‘auto’. The computed value of ‘overflow’ is equal to the computed value of ‘overflow-x’ if ‘overflow-y’ is the same; otherwise it is the pair of computed values of ‘overflow-x’ and ‘overflow-y’.
