The scroll button cannot get focus on the phone. Why?

Question

css

There is a site on which there is a slider, if you go from a computer, you can move it as you like, but if you go from your phone, it cannot get focus, and you can only poke at the area and it will move there, but will not follow your finger, maybe Is there a feature that will fix this?

Answer 1

Как к примеру сделать,чтобы пользователь нажал на эту кнопку и она получила фокус,и шла за его пальцами,а когда отпускает фокус уходит?
