OK, I coughed up some CSS, seems to resolve the line thickness issue

.accordion-divider { color: transparent !important; height: 0 !important; border-top: 1px solid black; /* This line creates the divider */ }

I'm having the same problem with the accordion divider thickness. Elle-Harrison Design's link still shows the problem in Chrome and Edge. I've tried everything, except CSS. Even made 9 separate accordion blocks, still too thick every 2nd line.
