有些网站右边滚动条是带颜色的，怎么做呀？？？

用css样式表:
body
{
    scrollbar-arrow-color: #ffffff;
    scrollbar-shadow-color: #006699;
    scrollbar-3Dlight-color: #cccccc;
    scrollbar-track-color: #ffffff;
    scrollbar-face-color: #006699;
    scrollbar-highlight-color: #006699;
    scrollbar-darkshadow-color: #006699;
}
