Here one I made to change the pulse effect on some of my website buttons…
.pulse {
box-shadow: 0 0 0 0 rgba(0,50,125,0.4);
animation: pulse 3s infinite;
animation-timing-function: ease-in-out;
will-change: transform;
}
.pulse:hover {
animation: none;
}
@keyframes pulse {
0% {
transform: scale(1);
-moz-box-shadow: 0 0 0 0 rgba(0,46,164,0.4);
box-shadow: 0 0 0 0 rgba(0,46,164,0.4);
}
50% {
transform: scale(1.05);
-moz-box-shadow: 0 0 0 40px rgba(255,0,0,0);
box-shadow: 0 0 0 40px rgba(255,0,0, 0);
}
100% {
transform: scale(1);
-moz-box-shadow: 0 0 0 0 rgba(255,0,0, 0);
box-shadow: 0 0 0 0 rgba(255,0,0, 0);
}
}
