Simply choose your background color of your item and specify the opacity separatly:

div { background-color:#000; opacity:0.8; }

Simply put:

.democlass {
    background-color: rgba(246,245,245,0);

That should give you a transparent background.

In the CSS write:

    background:#000000;
    opacity: 10; /* you can always adjust this */
