Botão Flutuante com Sombra

Neste tutorial vamos fazer um botão flutuante com sombra, ao passar o mouse ele flutua e aparece uma sombra na base do botão.

Vamos adicionar o Html

<!--Sem icone-->
<a href="#" class="btn float-shadow">Saiba mais</a>

<!--Com icone-->
<a href="#" class="btn float-shadow"><i class="icon icon-coffee"></i> Saiba mais</a>

Vamos Adicionar o Css:

.btn {

	padding:0.8em 1.5em;
	cursor:pointer;
	background-color:#33dbdf;
	text-decoration:none;
	font-weight:bold;
	border-radius:5px;
	color:#ffffff;
	transition:0.4s!important; 

}

.btn:hover { background-color:#17c4c8; }

/* Float Shadow */
.float-shadow {

  display: inline-block;
  vertical-align: middle;
  -webkit-transform: translateZ(0);
  transform: translateZ(0);
  box-shadow: 0 0 1px rgba(0, 0, 0, 0);
  -webkit-backface-visibility: hidden;
  backface-visibility: hidden;
  -moz-osx-font-smoothing: grayscale;
  position: relative;
  -webkit-transition-duration: 0.3s;
  transition-duration: 0.3s;
  -webkit-transition-property: transform;
  transition-property: transform;

}

.float-shadow:before {

  pointer-events: none;
  position: absolute;
  z-index: -1;
  content: '';
  top: 100%;
  left: 5%;
  height: 10px;
  width: 90%;
  opacity: 0;
  background: -webkit-radial-gradient(center, ellipse, rgba(0, 0, 0, 0.35) 0%, rgba(0, 0, 0, 0) 80%);
  background: radial-gradient(ellipse at center, rgba(0, 0, 0, 0.35) 0%, rgba(0, 0, 0, 0) 80%);
  /* W3C */
  -webkit-transition-duration: 0.3s;
  transition-duration: 0.3s;
  -webkit-transition-property: transform, opacity;
  transition-property: transform, opacity;

}

.float-shadow:hover, .float-shadow:focus, .float-shadow:active {
  
  -webkit-transform: translateY(-5px);
  transform: translateY(-5px);

}

.float-shadow:hover:before, .float-shadow:focus:before, .float-shadow:active:before {
