Can you make a vertical slider?

I get this request often.
Do you realize what you're asking? Because this is what it'd look like:

If you still want it, you can get it with card-mod and transform: rotate(-90deg), but it won't work well because the slider element used in Home Assistant isn't meant for vertical use.

It sounds like the main limiting factor is the built-in slider control because it doesn't handle the input coordinates properly when it's been rotated. I think what we truly need is a from-scratch vertical slider control. I'm quite surprised there isn't one in the community already. Someday when I have time to ramp up on the prerequisites I may need to roll my own control.
