[html] CSS3 scrollbar styling on a div

How can i style webkit scrollbars with CSS3?

I mean these properties

::-webkit-scrollbar {
    width: 12px;
}

::-webkit-scrollbar-track {
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3); 
    border-radius: 10px;
}

::-webkit-scrollbar-thumb {
    border-radius: 10px;
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.5); 
}

Here is my div tag

<div class="scroll"></div>

Here is my current CSS

.scroll {
   width: 200px; height: 400px;
   overflow: hidden;
}

.scroll {
   width: 200px; height: 400px;
   overflow: auto;
}

The problem with the css3 scroll bars is that, interaction can only be performed on the content. we can't interact with the scroll bar on touch devices.

You're setting overflow: hidden. This will hide anything that's too large for the <div>, meaning scrollbars won't be shown. Give your <div> an explicit width and/or height, and change overflow to auto:

.scroll {
   width: 200px;
   height: 400px;
   overflow: scroll;
}

If you only want to show a scrollbar if the content is longer than the <div>, change overflow to overflow: auto. You can also only show one scrollbar by using overflow-y or overflow-x.
