CSS text input form field design

Question

Once the focus is away the label transforms back, i just want that once the text is entered the transformation stays despite focus and if no text is entered it becomes the same as earlier, please help me add a piece of code in it so that it happens

<html>
<head>
<title>Index</title>
<style>
    body{
        font-family:Calibri;
        background-color:#FFFCD3; 
        height:1000px; 
        width:100%; 
        margin:0;}
    .container{
        padding:60px 0 0 0;
        margin:auto;
        background-color:#B4CDCA;
        height:485px;
        width:460px;}
    h1{
        font-size:36px; 
        padding:5px 50px 5px; 
        border-width:0 0 0 5px; 
        border-style:solid; 
        border-color:red; 
        font-family:Calibri; 
        margin:0px 0px 35px;}
    form div{
        margin:0 60px 50px;
        position:relative;}
    input{
        background-color:transparent; 
        width:100%; 
        height:100%; 
        outline:none; 
        padding:0; 
        margin:0; 
        border-width:0px 0px 2px 0px; 
        font-size:24px;
        line-height:60px;}
    .container button{
        font-family:Calibri; 
        margin:0px 114px; 
        padding:18px 100px; 
        background-color:transparent; 
        border:1px solid red; 
        outline:none;
        font-size:24px;}
    .container label{
        font-size:27px;
        position:absolute;
        top:0;
        line-height:60px;}
    input:focus + label{
        -webkit-transform:translate(-18px,-24px) scale(0.7,0.7);
        transition:ease-in,0.2s;}
</style>
</head>

<body>
<div class="container">
<h1>LOGIN</h1>
<form>
    <div>
    <input type="text" id="username" name="username" value=""/>
    <label for="username">Username</label>
    </div>
    <div>
    <input id="Password" type="password" name="password"/>
    <label>Password</label>
    </div>
    <button>
    GO
    </button>
</form>
</div>
</body>
</html>

use jquery. define class to add transformation (stays despite focus). Write a function which adds a class when focused and there is text. — SuperNova

css files do not support conditional statements. You could also research about sass (""Sass makes CSS fun again. Sass is CSS, plus nested rules, variables, mixins, and more, all in a concise, readable syntax"".) But I am not sure of the limitations in sass too.. — SuperNova

I have created a kinda forms like this with jquery, you can check with that. I hope we can perfectly done with jquery other than css.

//material contact form animation
$('.contact-form').find('.form-control').each(function() {
  var targetItem = $(this).parent();
  if ($(this).val()) {
    $(targetItem).find('label').css({
      'top': '10px',
      'fontSize': '14px'
    });
  }
})
$('.contact-form').find('.form-control').focus(function() {
  $(this).parent('.input-block').addClass('focus');
  $(this).parent().find('label').animate({
    'top': '10px',
    'fontSize': '14px'
  }, 300);
})
$('.contact-form').find('.form-control').blur(function() {
  if ($(this).val().length == 0) {
    $(this).parent('.input-block').removeClass('focus');
    $(this).parent().find('label').animate({
      'top': '25px',
      'fontSize': '18px'
    }, 300);
  }
});

You can do this by setting/removing the value attribute on the input element:

JS (PS: this is using PrototypeJS)

document.on('keyup', 'form input', function(ev, el) {
    if (!el.value || el.value.replace(/\s+/g, '') === '') {
        el.removeAttribute('value');
    } else {
        el.setAttribute('value', el.value);
    }
});

CSS

input[value] + label, /* <------------ checking for existence of value */
input:focus + label {
  -webkit-transform: translate(-18px, -24px) scale(0.7, 0.7);
  transition: ease-in, 0.2s;
}

FIDDLE

All I had to do is add this to my code

CSS
    input:valid + label {
        -webkit-transform:translate(-18px,-24px) scale(0.7,0.7);
        transition:ease-in,0.2s;}

HTML
   required

so that the css could validate it and style form accordingly.
