Side Bar #1, ver. #2

The font I chose for the links is Josefin Sans, I've included the google fonts code for it.

The colors are labeled as black and grey.

When applying this to your theme, I put it in my 435px box. Also, you will need to add a margin-left to this area of coding for your layout: .mygen { Background Properties }

Example:
.mygen { Background Properties }
table, tr, td { background-color:transparent; border:none; border-width:0;}
body {
        background-color:000000;
        background-image:url(https://i.imgur.com/26GSIbU.jpg);
        background-attachment: fixed;
        background-position:center center;
        background-repeat:no-repeat;
        margin-left: 75px;
        }
