Modify scrollbar in React without external dependencies

Question

I'm trying to modify the look of the scrollbar in my ReactJS application.

Basically, I would like to have something like the following:

I've tried to use CSS properties, e.g. -webkit-scrollbar, -webkit-scrollbar-track and -webkit-scrollbar-thumb, but I don't see any changes.

I searched online, but all I can find are 3rd party libraries which provide custom scrollbars.

Is there any way to do that without having to rely on an external dependency?

Answer 1

You can definitely do this using css only but browser support isn't that great which is why many JavaScript solutions exist. You can reduce the width of the -webkit-scrollbar-track by modifying the border-right and left:

border-left: 5px solid gray;
border-right: 5px solid gray;

As for the -webkit-scrollbar-thumb you can make it look as the image you provided by modifying the border radius:

border-radius: 10px;

the width of the scrollbar can be modified using the -webkit-scrollbar:

body::-webkit-scrollbar {
    width: 15px;
}

html {
  background: #2a2d46;
  height: 100%;
  overflow: hidden;
}
body {
  height: 100%;

  overflow: scroll;
  width: 80%;
  max-width: 600px;
  margin: 0 auto;
  padding: 3em;
  font: 100%/1.4 serif;
  border: 1px solid rgba(0, 0, 0, 0.25);
}
p {
  margin: 0 0 1.5em;
}

body::-webkit-scrollbar {
  width: 15px;
  background: #4d4e5a;
  color: #333;
}

body::-webkit-scrollbar-track {
  background: #595a62;
  border-left: 5px solid #2a2d46;
  border-right: 5px solid #2a2d46;
}

body::-webkit-scrollbar-thumb {
  background-color: #fff;
  border-radius: 10px;
}
