scroll top btn visibility

modified code

.scrolltop {
position: fixed;
right: 1rem;
bottom: 1.5rem;
display: flex;
justify-content: center;
align-items: center;
padding: .6rem;
background: rgba(6,156,84,.8);
border-radius: .4rem;
z-index: var(--z-tooltip);
transition: .3s ease-in-out;
visibility: visible;
opacity: 0;
}

.show-scroll {
opacity: 1;
}

Start by locating the stylesheet containing the .scrolltop and .show-scroll rules, then inspect the scroll-top button's behavior in the browser. The issue does not name a file, expected visibility behavior, or test; done should be defined by confirming the intended button visibility after clarifying the requirement.
