How to make slider text more opaque?

Sorry for double post, but this somebody might find helpful. I’ve tried to solve previous issue for a few hours now, and all I could come up with is this:

.nivo-caption {
background-color: rgba(0,0,0,0.7) !important;
}

It is not the solution I was searching for, but it is best I could do by now.

install Simple Custom CSS and past this code

.nivo-caption h3 {opacity: 1 !important ;}

thanks

That solved upper text, thank you – but what about the one in the gray box?

.nivo-caption p { opacity: 0.5 !important; }
