Custom scrollbar in only one div

Question

I want to have a custom scrollbar in Chrome.

So, I am using this sass:

::-webkit-scrollbar {
  width: 0.5em;
  height: 0.5em;
}

::-webkit-scrollbar-thumb {
  background-color: rgba(255,255,255,.1);
  border-radius: 3px;

  &:hover {
    background: rgba(255,255,255,.2);
  }
}

My problem is that I want this scroll style only in a specific div. But if I do this:

#boardslist {

  ::-webkit-scrollbar {
    width: 0.5em;
    height: 0.5em;
  }

  ::-webkit-scrollbar-thumb {
    background-color: rgba(255,255,255,.1);
    border-radius: 3px;

    &:hover {
      background: rgba(255,255,255,.2);
    }
  }

}

does not work. Any ideas?

If you do this for a class, you can do it as follows. The sidebar is the class given by the div that you want to allow scrolling.

.side_bar{
    padding-right: 20px; 
    margin-left: -12px;
    position: sticky;
    top: 0;
    height: 100vh;
    overflow-y: scroll;
    /* width */

}
.side_bar::-webkit-scrollbar {
        width: 5px;
    }

    /* Track */
.side_bar::-webkit-scrollbar-track {
        box-shadow: inset 0 0 2px grey; 
        border-radius: 10px;
    }

    /* Handle */
.side_bar::-webkit-scrollbar-thumb {
        background: rgb(7, 7, 7); 
        border-radius: 10px;
    }

    /* Handle on hover */
.side_bar::-webkit-scrollbar-thumb:hover {
        background: #009eb3; 
    }
