Unable to apply style to scrollbars using css-CodePudding

Currently, I have a scrollbar displaying over part of the page when there is a need for it.

I would like to apply styling to the scrollbar such that it doesn't look so bright and I can have the background area of the scrollbar to be transparent. Hence, I tried to apply styling to it. But the scrollbar still seems to be the same. To test if the styling is working, I gave some styles to the scroll based on this article:

Is it not possible to apply custom styling to the browser scrollbar ? Also, can I give scrollbar styling to a div element ? or It has to be at the root/body level?

Try to also add a ::-webkit-scrollbar, like this

body::-webkit-scrollbar {
    width: 12px;
}

Looks like you also need to add the ::-webkit-scrollbar to make styles work, I do not know the reason for this, and have not found an explanation. But the ::-webkit-scrollbar represent the whole scrollbar. An example:

body {
  width: 300px;
  height: 400px;
}

body::-webkit-scrollbar {
    width: 12px;
}

body::-webkit-scrollbar-track {
    box-shadow: inset 0 0 6px rgba(0, 0, 0, 0.3);
}

body::-webkit-scrollbar-thumb {
    background-color: red;
    outline: 1px solid slategrey;
}

This gives a transparent background on firefox as well

body {
  margin: 0;
  background: grey;
  height: 500px;
  overflow: overlay;
}

/* Firefox */
* {
  scrollbar-width: thin;
  scrollbar-color: green transparent;
}

/* Chrome, Edge, and Safari */
*::-webkit-scrollbar {
  width: 16px;
}

*::-webkit-scrollbar-track {
  background: rgba(0, 0, 0, 0);
}

*::-webkit-scrollbar-thumb {
  background-color: green;
  border-radius: 10px;
  border: 3px solid #ffffff;
}
