This seems to me not to be a Mendix related question? 

You'd better try your luck on Stack Overflow I think.. https://stackoverflow.com/questions/29698207/how-to-make-a-custom-scroll-bars-in-ie

The look and feel of the scrollbar can be customized to your hearts content.

Hi Shaik,

you can append this custom css code in your scss file and use “.slim-scroll” class for where ever u want to enable this scroll. 

.slim-scroll::-webkit-scrollbar{
    width: 8px;
  background-color: gray;
 }
 .slim-scroll::-webkit-scrollbar-thumb{
    border-radius: 8px;
    box-shadow: inset 0 0 6px rgba(0,0,0,.3);
    background-color: black;
 }
 .slim-scroll::-webkit-scrollbar-track{
 box-shadow: inset 0 0 6px rgba(0,0,0,0.3);
  border-radius: 10px;
  background-color: gray;
 }
