how to style a scroll bar

is there a way to style my scroll bar (see attached). I want to style it to match my slideshow. From what I researched online, using CSS to style scroll bars isn't supported by modern browsers. I am looking for an easy way to do that using j-query/js. Any useful references or suggestion on how to go about doing it will be appreciated.

Here is the link to the page:

Here is the related CSS property (I just set the overflow property to auto):
#slidearea {
    float: left;
    height: 81px;
    margin-left: 5px;
    overflow-x: auto;
    position: relative;
    width: 456px;
    overflow-y: hidden;
}

Thanks in advance for the help!
