How to custom shadow width?

DangDKhanh-2637 751 Reputation points

after showing the tooltip,
its shadow is quite small and looks very dark, is there any way I can disperse the shadow?

I have read this post but it is quite confusing because I don't know what is real solution?

Is it possible to achieve this? (something that can adjust the opacity)

Thanks you.
