We're doing a sensory evaluation and would be relying on multiple numerical input (sliders). Can somebody help me on how to add a custom label/mark/line on the middle of the slider?
The value of the marker would not have any effect on the results, I just basically want to show a standard value so the participants would have a reference. Can I do this on CSS?
Also, since the standard value changes per question, do you think it is possible to have a custom input for the marker?
