i am using this css code for 1st iPod Touch.
#directions{
overflow-y: scroll;
overflow-x: scroll;
}
#directions::-webkit-scrollbar {
background: transparent;
height: 10px;
overflow: visible;
width: 10px;
}
#directions::-webkit-scrollbar-thumb {
background-color: rgba(0, 0, 0, 0.2);
-webkit-border-radius:5px;
}
#directions::-webkit-scrollbar-thumb:hover{
background-color: rgba(0, 0, 0, 0.6);
}
#directions::-webkit-scrollbar-corner {
background: transparent;
}
In iOS5,
-webkit-overflow-scrolling: touch;
maybe, You will allow one finger to scroll. I did not try it yet.
