Hi @vl3d,
You could do this within the custom code editor using a keyframe animation.
@keyframes glow {
0% { box-shadow: 0 0 -10px red; }
40% { box-shadow: 0 0 20px red; }
60% { box-shadow: 0 0 20px red; }
100% { box-shadow: 0 0 -10px red; }
}
.glowing-button {
animation: glow 5000ms infinite;
}
Hope this helps @vl3d
