thanks for the reply but this link doesn't address my problem. I guess my question is not very clear about the problem.

What i want is a modal panel so that when it appears, page should be disabled with the blocking div. What i want is to change the style options for the modal panel. Like the borders of the modal panel. I want them to be of size zero. and the background color of the modal panel which is white (not of the blocking div).
means i want to change the style of the modal panel, not to disable the blocking div.
How can i do this?

thanks.

i have made model panel look like transparent by defining

.rich-mpnl-body {
background-color: #E7E7E7;
}
where the back ground color is same as of the blocking div so that it may look transparent.

however i am unable to change the color properties for the model panel border color and its shadow color. I have tries but failed. How to do this now???

Thanks

I have tried alot to change the color of the borders of the modal panel but failed. I changed its CSS properties according to the rich faces modal panel guide but no use. any idea what properties to change?? I am totally stuck here....
