I am trying to achieve a floating placeholder functionality. Everything works fine with the code I have written except for the fact that when there is an email field and I try to add a wrong entry which is not of an email format and i shift focus from the input box, the floating text still appears. You can check the codepen link

Belew is my code:-

.-input-container {
    max-width: 540px;
    padding-bottom: 30px;
    margin-top: 30px;
}

input.-textbox {
    width: 100%;
    border-radius: 40px;
    background-color: #f5f5f5;
    border: 1px solid #dddddd;
    padding: 16px 30px;
    font-size: 16px;
    color: #555555;
    font-family: OpenSans;
    font-weight: normal;
    font-style: normal;
    font-stretch: normal;
    line-height: 1.88;
    letter-spacing: normal;
    text-align: left;
}

input.-textbox:focus{
    outline: none;
    box-shadow: none
}

input.-textbox:focus ~ .floating-label,
input.-textbox:not(:focus):valid ~ .floating-label {
  top: 8px;
  bottom: 10px;
  left: 45px;
  font-size: 10px;
  opacity: 1;
  line-height: 2.1;
  font-family: OpenSans;
}

input.-textbox ~ .floating-label {
  position: absolute;
  pointer-events: none;
  left: 45px;
  top: 18px;
  transition: 0.2s ease all;
}

Try this:

.-input-container {
    max-width: 540px;
    padding-bottom: 30px;
    margin-top: 30px;
}

input.-textbox {
    width: 100%;
    border-radius: 40px;
    background-color: #f5f5f5;
    border: 1px solid #dddddd;
    padding: 16px 30px;
    font-size: 16px;
    color: #555555;
    font-family: OpenSans;
    font-weight: normal;
    font-style: normal;
    font-stretch: normal;
    line-height: 1.88;
    letter-spacing: normal;
    text-align: left;
    &:focus{
      outline: none;
      box-shadow: none
    }
}

<div class="-input-container col-xl-6 col-lg-6 col-md-12 col-sm-12 col-12 ">
  <input type="email" class="-textbox form-control" placeholder="E-postadress" required="">
</div>

Use javascript in it. Try this

$('input').on('focusin', function() {
  $(this).parent().find('span').addClass('test2');
});

$('input').on('focusout', function() {
  if (!this.value) {
    $(this).parent().find('span').removeClass('test2');
  }
});

.-input-container {
  max-width: 540px;
  padding-bottom: 30px;
  margin-top: 30px;
}

input.-textbox {
  width: 100%;
  border-radius: 40px;
  background-color: #f5f5f5;
  border: 1px solid #dddddd;
  padding: 16px 30px;
  font-size: 16px;
  color: #555555;
  font-family: OpenSans;
  font-weight: normal;
  font-style: normal;
  font-stretch: normal;
  line-height: 1.88;
  letter-spacing: normal;
  text-align: left;
}

input.-textbox:focus {
  outline: none;
  box-shadow: none
}

input.-textbox:focus~.floating-label,
input.-textbox:not(:focus):valid~.floating-label, {
  top: 18px;
  bottom: 10px;
  left: 45px;
  font-size: 10px;
  opacity: 1;
  line-height: 2.1;
  font-family: OpenSans;
}

input.-textbox~.floating-label {
  position: absolute;
  pointer-events: none;
  left: 45px;
  top: 18px;
  transition: 0.2s ease all;
}
.test2{
 margin-top:-20px;
 line-height:2.1;
 font-size:10px;
  font-family: OpenSans;
}

It is simple with some Javascript and minor changes in styles. Try this one.

$(document).ready(function () {
    $('.-textbox').click(function (){
        $(this).siblings('span').addClass('active');
    });
    $('.-textbox').blur(function(){
        if($('.-textbox').val()=== ''){
            $(this).siblings('span').removeClass('active');
        }
    });
});

.-input-container {
    max-width: 540px;
    padding-bottom: 30px;
    margin-top: 30px;
    position: relative;
}

input.-textbox {
    width: 100%;
    border-radius: 40px;
    background-color: #f5f5f5;
    border: 1px solid #dddddd;
    padding: 16px 30px;
    font-size: 16px;
    color: #555555;
    font-family: OpenSans;
    font-weight: normal;
    font-style: normal;
    font-stretch: normal;
    line-height: 1.88;
    letter-spacing: normal;
    text-align: left;
    &:focus{
        outline: none;
        box-shadow: none
    }
}
input.-textbox ~ .floating-label {
    position: absolute;
    pointer-events: none;
    left: 45px;
    top: 18px;
    transition: 0.2s ease all;
}
input.-textbox ~ .floating-label.active{
    top: 8px;
    bottom: 10px;
    left: 45px;
    font-size: 10px;
    opacity: 1;
    line-height: 2.1;
    font-family: OpenSans;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="-input-container col-xl-6 col-lg-6 col-md-12 col-sm-12 col-12 ">
    <input type="email" class="-textbox form-control" required="">
