Css z-index problem

I have an issue where one image is infront of another and z-index doesnt seem to change it. I am trying to make it so the logo is on top of the gray bars image.

Can anyone explain to me why this is not working?

Answer 1

z-index only works with position : relative/absolute/fixed so give position:relative to your logo.

In this, I changed in the markup because we never put block element inside an inline element. <a> is an inline element & h1 is a block element.
