Animate button with two backgrounds

Im trying to do the same button but without the need to make hover (running the animated background all the time).

I've tried different approach like using background-clip, shadows, etc but unfortunately without success.

Maybe if I use another element like a div and span can work but I really want to do it with a button.

Codepen

html,
body {
  margin: 0;
  padding: 0;
  width: 100%;
  height: 100vh;
  display: flex;
  flex-direction: row;
  justify-content: center;
  align-items: center;
  background: #000;
}

.glow-on-hover {
  width: 220px;
  height: 50px;
  border: none;
  outline: none;
  color: #fff;
  background: #111;
  cursor: pointer;
  position: relative;
  z-index: 0;
  border-radius: 10px;
}

.glow-on-hover:before {
  content: '';
  background: linear-gradient(45deg, #ff0000, #ff7300, #fffb00, #48ff00, #00ffd5, #002bff, #7a00ff, #ff00c8, #ff0000);
  position: absolute;
  top: -2px;
  left: -2px;
  background-size: 400%;
  z-index: -1;
  filter: blur(5px);
  width: calc(100% + 4px);
  height: calc(100% + 4px);
  animation: glowing 20s linear infinite;
  opacity: 0;
  transition: opacity .3s ease-in-out;
  border-radius: 10px;
}

.glow-on-hover:active {
  color: #000
}

.glow-on-hover:active:after {
  background: transparent;
}

.glow-on-hover:hover:before {
  opacity: 1;
}

.glow-on-hover:after {
  z-index: -1;
  content: '';
  position: absolute;
  width: 100%;
  height: 100%;
  background: #111;
  left: 0;
  top: 0;
  border-radius: 10px;
}

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

<button class="glow-on-hover" type="button">HOVER ME, THEN CLICK ME!</button>

What is making your ::before pseudo-element to hide when it's not hovered is opacity:0. If you remove it, you will have the desired effect. Also, you might want to remove the glow-on-hover:hover:before selector since it's not going to be any use.
