Is it possible to have 2 different font sizes in one input placeholder in CSS?

something like this design:  different font sizes in one input placeholder

In regular html you can make it with span,:before,&:after and etc.

but in input you cant make all this things so i want to understand if its possible...

To apply different styles in the same placeholder is not possible.

What you can do however is either use pseudo elements or a div which behaves as a placeholder and hide/show it when the input is focussed.

This might help:

$("#input").keyup(function() {
  if ($(this).val().length) {
    $(this).next('.placeholder').hide();
  } else {
    $(this).next('.placeholder').show();
  }
});
$(".placeholder").click(function() {
  $(this).prev().focus();
});
.placeholder {
  position: absolute;
  margin: 7px 8px;
  color: #A3A3A3;
  cursor: auto;
  font-size: 14px;
  top: 7px;
}
.small {
  font-size: 10px;
}
input {
  padding: 5px;
  font-size: 11pt;
  position: relative;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="input" type="text" />
<div class="placeholder">Email <span class="small">address</span>
</div>

CSS only Solution

.input-field {
  position: relative;
  display: inline-block;
}

.input-field > label {
  position: absolute;
  left: 0.5em;
  top: 50%;
  margin-top: -0.5em;
  opacity: 1;
  display: none;
}

.input-field > input[type=text]:placeholder-shown + label {
  display: block;
}

.input-field > label > span {
  letter-spacing: -2px;
}

.first-letter {
  color: red;
  font-size:100%;
}

.second-letter {
  color: blue;
  font-size:50%;
}

.third-letter {
  color: orange;
  font-size:75%;
}

.fourth-letter {
  color: green;
  font-size:100%;
}

.fifth-letter {
  color: yellow;
  font-size:25%;
}
<div class="input-field">
  <input id="input-text-field" type="text" placeholder=" "></input>
  <label for="input-text-field">
    <span class="first-letter">H</span>
    <span class="second-letter">E</span>
    <span class="third-letter">L</span>
    <span class="fourth-letter">L</span>
    <span class="fifth-letter">O</span>
  </label>
</div>

JS solution

    addListenerMulti(document.getElementById('input-text-field'), 'focus keyup', blurme);

    function blurme(e) {
      var element = e.currentTarget;
      element.classList[(element.value.length !== 0) ? "add" : "remove"]('hide-placeholder');
    }

    function addListenerMulti(el, s, fn) {
      s.split(" ").forEach(function(e) {
        return el.addEventListener(e, fn, false)
      });
    }
    .input-field {
      position: relative;
      display: inline-block;
    }
    .input-field > label {
      position: absolute;
      left: 0.5em;
      top: 50%;
      margin-top: -0.5em;
      
    }
    .hide-placeholder + label {
      display: none;
    }
    .input-field > label > span {
      letter-spacing: -2px;
    }
    .first-letter {
      color: red;
      font-size:100%;
    }
    .second-letter {
      color: blue;
      font-size:100%;
    }
    .third-letter {
      color: orange;
      font-size:100%;
    }
    .fourth-letter {
      color: green;
      font-size:50%;
    }
    .fifth-letter {
      color: black;
      font-size:50%;
    }
    <div class="input-field">
      <input id="input-text-field" type="text">
      <label for="input-text-field">
        <span class="first-letter">H</span>
        <span class="second-letter">E</span>
        <span class="third-letter">L</span>
        <span class="fourth-letter">L</span>
        <span class="fifth-letter">O</span>
      </label>
    </div>
