Hello,
You can use CSS with ::-webkit-scrollbar:

.gantt_hor_scroll::-webkit-scrollbar {
    height: 17px;
}

.gantt_hor_scroll::-webkit-scrollbar-thumb {
    background-color: red;
    border-radius: 5px;
}

.gantt_hor_scroll::-webkit-scrollbar-track {
    background-color: yellow;
}

Please see an example: DHTMLX Snippet Tool
