html - CSS3 scrollbar styling on a div

Question

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;
}    

Answer 1

Setting overflow: hidden hides the scrollbar. Set overflow: scroll to make sure the scrollbar appears all the time.

To use the ::webkit-scrollbar property, simply target .scroll before calling it.

.scroll {
   width: 200px;
   height: 400px;
    background: red;
   overflow: scroll;
}
.scroll::-webkit-scrollbar {
    width: 12px;
}

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

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