Strange CSS ''overlay effect'' on Mobile Browsers

Question

I've just learned to make animation with CSS. On Desktop Chrome everything is OK. But when I checked it out on Chrome for Android - there's some strange overlay effect when clicking.

Code

.btn {
  -webkit-appearance: none;
  -moz-appearance: none;
  appearance: none;
  display: block;
  position: relative;
  margin: 0 auto;
  outline: none;
  border: none;
  background-color: #ff8800;
  padding: 25px 65px;
  font-size: 25px;
  text-transform: uppercase;
  border-radius: 25px;
  box-shadow: 0 8px #ff6600;
  cursor: pointer;
  top: 0;
  transition: all .3s;
}

.btn:hover {
  top: 3px;
  box-shadow: 0 5px #ff6600;
}

.btn:active {
  top: 8px;
  box-shadow: none;
}

<button class="btn">Click Me!</button>

How I can get rid of this strange overlay on mobile browser? Thanks.

@JohnDoherty that rule would make button unclickable and non-functional — Teo Dragovic, Apr 21 '18 at 12:03
@TeoDragovic user-select stops the user from selecting text, the button would still be clickable — John Doherty, Apr 21 '18 at 16:01

Add -webkit-tap-highlight-color: transparent; to your .btn class (or even globally to body if you want to prevent this on all clickable elements).
