CSS Help!
So my band website is using bootstrap and I have created a div for the background and applied the background in CSS, see below.

background-image: url(...);
height: 100%;
z-index: -1;
background-position: center;
background-repeat: no-repeat;
background-size: cover;

I am trying to add an image over the top of it and tried to use the img-fluid class but the image I'm adding is sitting below the background class not over the top.
I'm pulling my hair out hahaha
