There are 7 different scrollbar options to use:

::-webkit-scrollbar-button {/ * 2 - button * /}
::-webkit-scrollbar-track {/ * 3 - track * /}
::-webkit-scrollbar-track-piece {/ * 4 - the visible part of the track */}
::-webkit-scrollbar-thumb {/ * 5 - slider * /}
::-webkit-scrollbar-corner {/ * 6 - corner * /}
::-webkit-resizer {/ * 7 - resizing * /}

For what you're trying to achieve, you can do this:

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

::-webkit-scrollbar-track {
    box-shadow: inset 0 0 6px rgba(0, 0, 0, 0.3);
    border-radius: 10px;
}

::-webkit-scrollbar-thumb {
    box-shadow: inset 0 0 6px rgba(0, 0, 0, 0.5);
    border-radius: 10px;
}
