  transition: box-shadow 0.3s ease;
}

.glow-button:hover {
  box-shadow: 0 0 20px #4CAF50;
}

  background: linear-gradient(90deg, #ff0000, #ff7300, #fffb00, #48ff00, #00ffd5, #002bff, #7a00ff, #ff00c8, #ff0000);
  background-size: 400%;
  border-radius: 50px;
  color: white;
  padding: 15px 30px;

  background: inherit;
  background-size: 400%;
  border-radius: 50px;

  animation: glow 8s linear infinite;
}

@keyframes glow {

  50% { background-position: 400% 0; }
  100% { background-position: 0 0; }
}

  background: transparent;
  padding: 20px;
  border: 4px solid #fff;
