change opacity in mask behind modal window

hi,
anyone can help me?

Change the CSS

Code:

---

.x-mask {
    opacity : .9
}

---

yea,
but in this case i change all opacity in my project to .9.
i need to set opacity to specific object.
ex:
1- for loading (grids etc..) mask opacity 0.5
2- for modal window (my login) opacity 1

sorry for my english

You will need to add an additional css class to the mask element to handle this situation.

tnx...

i set new css with new name ext:

.new-mask {
background-color: transparent;
filter: none;
opacity: 1;
}

but how set to the modal window???
cls: ?

Did you resolve this?
