Down arrow click not working with ripple rings animation - html

Question

I have a down arrow with rings in a ripple effect around it. The down arrow click doesn't work with the rings around it, but if I remove the rings, the click function works normally.
This is the webpage: https://rimildeyjsr.github.io/St.Anthony-Website/
Any ideas how to fix it?
CSS:
body{
background: red;
}
.down-arrow {
display: none;
position: absolute;
left: 0;
right: 0;
margin: 0 auto;
top: 50%;
z-index: 5;
border-radius: 50%;
height: 80px;
width: 80px;
}
.ring {
border: 2.5px solid white;
-webkit-border-radius: 50%;
height: 80px;
width: 80px;
position: absolute;
left:0;
right: 0;
top:50%;
z-index: 5;
margin: 0 auto;
-webkit-animation: pulsate 2s ease-out;
-webkit-animation-iteration-count: infinite;
-webkit-animation-delay: 2s;
opacity: 0.0;
}
.ring2 {
-webkit-animation-delay: 1.4s;
}
#-webkit-keyframes pulsate {
0% {-webkit-transform: scale(0,0); opacity: 1;}
100% {-webkit-transform: scale(1.2,1.2); opacity: 0;}
}
HTML:
<img src="images/down-arrow.png" alt="down arrow for navigation" class="img-responsive down-arrow animated slideInDown">
<div class="ring"></div>
<div class="ring ring2"></div>

z-index: 15;
border-radius: 50%;

.ring2 {
-webkit-animation-delay: 1.4s;
}
#-webkit-keyframes pulsate {
0% {-webkit-transform: scale(0,0); opacity: 1;}
100% {-webkit-transform: scale(1.2,1.2); opacity: 0;}
