A checkbox on my form looks like a text Input

enter image description here[I have this code on my html fileÑ

<div class="input" style="height:20px">
        <img src="../img/pass.png" class="middle iconColor">
        <input type="password" class="inputNoBorder" placeholder="Contraseña" id="login-pass" />
    </div>       
     <div>
          <!-- An element to toggle between password visibility -->
        <input type="checkbox" ><span>Show password</span>
     </div>
    <br><br>
    <button class="blueButton" id="login">Iniciar Sesión</button>
    <br>

and it runs by nodeserver.js and appears like a text box]2
