Overlay over image on hover - html

Question

I am unsure of what I am doing wrong trying to get a transparent overlay to appear over an image on hover. Initially, I attempted a javascript approach, but that didn't work, so I figured I would try a more light-weight css approach.
Does anyone see why this is not working?
.section2-box {
display: inline-block;
width: 50%;
height: 50%;
border-bottom: 4px solid #FFF;
border-right: 4px solid #FFF;
box-sizing: border-box;
position: relative;
}
.fadeHover {
transition: all .35s ease;
-webkit-transition: all .35s ease;
transition-delay: 0.10s;
-webkit-transition-delay: 0.10s;
height: 100%;
width: 100%;
top: 0;
left: 0;
right: 0;
}
.fadeHover:hover .overlay {
background-color: rgba(0, 0, 0, 0.6);
z-index: 1;
height: 100%;
width: 100%;
top: 0;
left: 0;
right: 0;
position: absolute;
cursor: pointer;
}
.fadeHover-title {
font-family: 'Raleway', sans-serif;
font-weight: 600;
font-size: 1.3rem;
color: #FFF;
display: none;
}
.fadeHover-title.activeHover {
opacity: 1;
}
.fadeHover-description {
font-size: 1.1rem;
color: #FFF;
font-family: 'Open Sans', sans-serif;
display: none;
}
.fadeHover-description.activeHover {
opacity: 1;
}

Regardinf your question on the comment : change the text color of the element from a rgba with 0 alpha to a 1 alpha:
.section2-box {
display: inline-block;
width: 50%;
height: 50%;
border-bottom: 4px solid #FFF;
border-right: 4px solid #FFF;
box-sizing: border-box;
position: relative;
}
.fadeHover {
transition: all .35s ease;
-webkit-transition: all .35s ease;
transition-delay: 0.10s;
-webkit-transition-delay: 0.10s;
height: 100%;
width: 100%;
top: 0;
left: 0;
right: 0;
}
.fadeHover .overlay {
z-index: 1;
height: 100%;
width: 100%;
top: 0;
left: 0;
right: 0;
position: absolute;
cursor: pointer;
}
.fadeHover-title {
font-family: 'Raleway', sans-serif;
font-weight: 600;
font-size: 1.3rem;
color: rgba(255,255,255,0);

}
.fadeHover:hover .fadeHover-title {
