Some problem about nested div

Now, here is two div, one contain another one, if you set parent div filters(such as FILTER: alpha(opacity=80)、opacity: 0.8、-moz-opacity: 0.8), child div's oversteop part will be hidden, this phenomenon equal to set parent div overflow property to "hidden"(only in IE). On the other hand, child div also inherit parent filter property(IE、Firefox), obviously i didn't set any property of child div that as mentioned above, i don't this's why? If who know and had seen this article, please tell me. Thank you very much!
