Overflow Text: Scrollbar

Im working on a site for a client and they have a lot of text information. Is there a way to make the overflow text scrollbar more prominent?

In case you have a scrollbar on text, as I can understand, you are using parent element like containers or section with overflow content set to scroll and place the text in it
Unfortunately, there is no option to make scrollbar more prominent, it got default browser settings
In case you mean something else, please share more details with us =)
