custom css scrollbar issue with webkit browsers

Problem

I have created a custom scroll bar which seem to be working fine on firefox, however i'm having an issue with my scroll appearing on screen in a webkit browser. Click here

 #product-desc{
        top: 270px;
        left: 20px;
        right: 20px;
        bottom: 20px;
        height: 90px;
        max-width: 350px;
        overflow-x: hidden;
        overflow-y: scroll;
    }


    #product-desc :: -webkit-scrollbar{
        width: 12px;
    }

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

    #product-desc :: -webkit-scrollbar-thumb{
        border-radius: 10px;
         -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.5);
         color: #000;
        }

Does anyone know how i can resolve this issue?

Solution

These are the pseudo elements themselves. The actual parts of the scrollbars.

::-webkit-scrollbar              { /* 1 */ }
::-webkit-scrollbar-button       { /* 2 */ }
::-webkit-scrollbar-track        { /* 3 */ }
::-webkit-scrollbar-track-piece  { /* 4 */ }
::-webkit-scrollbar-thumb        { /* 5 */ }
::-webkit-scrollbar-corner       { /* 6 */ }
::-webkit-resizer                { /* 7 */ }
