Quite seldom that I need a slider for input but when I do, I want it to look specific.
Well, I had seen that elm-ui has possibilities to design both the background and the knob of a slider. So for a game where users are selecting probability, I came up with this solution.
The user can adjust value by pressing and moving, as slider normally work.
The knob, or thumb, is invisible but that required that the focus style was set or a small blue square would appear.

As you can see in the code, I used
elm/svg but it is of course possible to use an external image. Mind that some of the function names in that package overlap, eg
style, with other packages functions.
When I was looking for a linear gradient, I bumped into this site https://cssgradient.io/ where you can interactively design your gradient.
