These do not overlay on top of the content, but appear next to it. > Unobtrusive scrollbars: scrollbars that sit on top of the content. These don’t subtract screen real estate away from the container they belong to. I work mostly on the front end, and I recently ran into a bug where a scrollbar would alternate between these two behaviors depending on screen width, the page's CSS, and when the DOM was redrawn. I'm generally interested in moving away from FE work, and I must admit that part of it is to increase the distance between me and scrollbars.
