Marjorie,
You can make the scroll bars more visible. Go to the Theme Options page and choose the Styling tab. Scroll down to the Custom CSS box and paste this:
.nano > .pane {
background: rgba(0,0,0,.5);
width: 12px;
opacity: .6;
}
.nano > .pane > .slider {
background: rgba(0,0,0,.75);
}
Update your settings and see if that works better for you. It’s possible to make them even more opaque without hovering. Just change the opacity: .6
above to a higher number (on a scale from 0 to 1). You can make it wider by changing the width too.
If you run into trouble, let me know,
Bill
