Put the circle image within the card that holds the background. So before the end </div> of the BG card, add in the circle. You can make any image a circle by adding class="rounded-circle" and setting a height/width!
Except ontop of the background and to the left. I have a code idea for personal use, but I only have my background fixed, and no understanding how to get a image of a circle icon to be uh there.
Also Shinsou, if you have a qualm with this question I can take it down ;u;
