I am bit confused to achieve following thing 1. disable visibility of one parent div 2. but child div visibility are allowed by another code
<div style="background-color:#999 ; height:80px;visibility:hidden">
<div style="background-color:#550; height:30px;"></div>
<div style="background-color:#900; height:30px;visibility:visible"></div>
</div>
I want to hide all the child div if parent div is not visible or any suggestion for this.
