how to style ScrollView?

I want to make the drag bar fatter, and I tried many combinations, is there a way to make it fatter as it is too thin right now?

 

Here's the set of selectors I used to make the vertical scroll bar 60px wide. You can tweak the values to suit. For my scroll bars I also swapped out the arrow images and made some color tweaks. The CSS for the scroll bars uses absolute positioning rather than flex for all its layout so you end up having to override everything.

Code (CSharp):

1.  
2. .unity-scroller--vertical {
3.     width: 60px;
4.     border-left-width: 2px;
5. }
6.  
7. .unity-scroller--vertical > .unity-scroller__high-button {
8.     width: 100%;
9.     height: 60px;
10. }
11.  
12. .unity-scroller--vertical > .unity-scroller__low-button {
13.     width: 100%;
14.     height: 60px;
15. }
16.  
17. .unity-scroller--vertical > .unity-scroller__slider {
18.     width: 100%;
19.     margin-top: 70px;
20.     margin-bottom: 70px;
21. }
22.  
23. .unity-scroller--vertical .unity-base-slider__tracker {
24.     width: 100%
25. }
26.  
27. .unity-scroller--vertical .unity-base-slider__dragger {
28.     width: 75%;
29.     align-self: center;
30. }
31.  

 

thanks!
