I'm using the default theme which has an opaque gradient overlay, over the main hero (banner) image. The problem is the overlay is too dark. How can I remove or lighten the overlay?
I've tried making a custom css modification for .slide-item {background:linear-gradient(rgba(0, 0, 0, 0), rgba(0, 0, 0, 0.7)),rgba(0, 0, 0, 0)!important;}, but it does not make a difference.
Help appreciated.
