give a class or id to the the element that you want to apply the scrollbar colors to then in the css define the colors under that specific class or element, mind you that scrollbar colors only work in IE/PC and maybe one other browser, and then define the colors for the html element in css
Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Scrollbar colors</title>
<style type="text/css">
<!--
html {
scrollbar-3dlight-color : #FFFFFF;
scrollbar-arrow-color : #FFFFFF;
scrollbar-base-color : #000000;
scrollbar-darkshadow-color : #000000;
scrollbar-face-color : #FF0000;
scrollbar-highlight-color : #FFFFFF;
scrollbar-shadow-color : #CCCCCC;
scrollbar-track-color : #000000;
}
div#content {
height:300px;
width:300px;
margin:auto;
overflow:auto;
scrollbar-3dlight-color : #FFFFFF;
scrollbar-arrow-color : #FFFFFF;
scrollbar-base-color : #000000;
scrollbar-darkshadow-color : #000000;
scrollbar-face-color : #0000FF;
scrollbar-highlight-color : #FFFFFF;
scrollbar-shadow-color : #CCCCCC;
