Here is what I’ve tried so far…
I could get rid of the overlay completely along with the arrow by doing this:
figure .overlay {
display: none;
}
I could not however change the color or transparency.
But when I did this by accident
figure.overlay{
width: auto !important;
max-width: 100% !important;
margin-left: auto;
margin-right: auto;
}
I got rid of the blue overlay and the arrow was pushed to the left side of the thumbnail. But I have no idea what happened to the blue overlay nor why the arrow was pushed to the left.This was done by accident.
