Is it possible to have vertical grid lines to be shown on slider bar?

FFischer did you ever find a solution for this?

This code is the closest I have gotten to answering this question.
.slider-container:after {
  content:"";
  position: absolute;
  z-index: -1;
  top: 50px;
  bottom: 0;
  left: 50%;
  border-left: 2px solid #9b9b9b;
  transform: translate(-50%);
}

Apart from this, I have not found anything useful.

David_UB,
You can write JS to add ticks that match the grid lines:

Oh, I see.
TomG can you share the JS code you are using? I don't have a lot of experience with JS and will be greatly appreciated.
Thanks!
