Try with this code.

HTML:

  <div class="main_div">
  <div class="group">
      <input type="text" required="required"/>
      <label>Name</label>
    </div>
</div>

CSS:

.main_div{
    padding: 30px;
}
input,
textarea {
    background: none;
    color: #c6c6c6;
    font-size: 18px;
    padding: 10px 10px 10px 15px;
    display: block;
    width: 320px;
    border: none;
    border-radius: 10px;
    border: 1px solid #c6c6c6;
}
input:hover{
    border: 3px solid black;
}
input:focus,
textarea:focus {
    outline: none;
    border: 3px solid black;
}
input:focus ~ label, input:valid ~ label,
textarea:focus ~ label,
textarea:valid ~ label {
    top: -5px;
    font-size: 12px;
    color: #000;
    left: 11px;
}
input:focus ~ .bar:before,
textarea:focus ~ .bar:before {
    width: 320px;
}

input[type="password"] {
    letter-spacing: 0.3em;
}
.group{
    position: relative;
}
label {
    color: #c6c6c6;
    font-size: 16px;
    font-weight: normal;
    position: absolute;
    pointer-events: none;
    left: 15px;
    top: 12px;
    transition: 300ms ease all;
    background-color: #fff;
    padding: 0 2px;
}

Answer 2

CSS Only solution; use combination of sibling selector ~ on the label and :valid pseudo selector on the input.

body {
  margin: 10px;
}

.form-group>label {
  bottom: 34px;
  left: 15px;
  position: relative;
  background-color: white;
  padding: 0px 5px 0px 5px;
  font-size: 1.1em;
  transition: 0.2s;
  pointer-events: none;
}

.form-control:focus~label {
  bottom: 55px;
}

.form-control:valid~label {
  bottom: 55px;
}
