#1. Install this free tool and find the ID of the section where you want to make the arrow appear.
In my example, ID is:
- section[data-section-id=”663506bb63188504d30b7d9a”]

#2. Use this code to Custom CSS box
section[data-section-id="663506bb63188504d30b7d9a"] {
position: relative;
}
section[data-section-id="663506bb63188504d30b7d9a"]:after {
content: "";
position: absolute;
left: 50%;
bottom: 30px;
display: block;
text-align: center;
font-size: 100px;
z-index: 100;
text-decoration: none;
text-shadow: 0;
width: 30px;
height: 30px;
border-bottom: 4px solid white;
border-right: 4px solid white;
z-index: 9;
left: 50%;
-webkit-transform: translate(-50%, 0%) rotate(45deg);
-moz-transform: translate(-50%, 0%) rotate(45deg);
transform: translate(-50%, 0%) rotate(45deg);
-webkit-animation: fade_move_down 4s ease-in-out infinite;
-moz-animation: fade_move_down 4s ease-in-out infinite;
animation: fade_move_down 4s ease-in-out infinite;
}
/*animated scroll arrow animation*/
@-webkit-keyframes fade_move_down {
0% { -webkit-transform:translate(0,-10px) rotate(45deg); opacity: 0; }
50% { opacity: 1; }
100% { -webkit-transform:translate(0,10px) rotate(45deg); opacity: 0; }
}
@-moz-keyframes fade_move_down {
0% { -moz-transform:translate(0,-10px) rotate(45deg); opacity: 0; }
50% { opacity: 1; }
100% { -moz-transform:translate(0,10px) rotate(45deg); opacity: 0; }
}
@keyframes fade_move_down {
0% { transform:translate(0,-10px) rotate(45deg); opacity: 0; }
50% { opacity: 1; }
100% { transform:translate(0,10px) rotate(45deg); opacity: 0; }
}
