The problem of mobile web scrollbar

when the div is displayed in the mobile browser, the scroll bar does not appear, but the content can be scrolled. Set div overflow:auto;

when I made the page by myself, I found that the mobile div setting overflow:auto; or overflow:scroll; results that the excess part of the div does not display the scroll bar, but sliding the finger up and down div can scroll the content, but the content scrolling will not be as smooth as the scroll bar, but as much as you slide, you will scroll as much as you do. After leaving the finger, you will stop scrolling immediately, and there will not be a buffer time to slow down and stop.
I would like to ask how to solve this. I want to let div get out of the scroll bar normally, just like the normal scroll bar. After the finger stops, there will be a process of deceleration
