            display: grid;
            place-items: center;
            overflow-x: hidden;
        }

        .child_div {
            width: 26rem;
            height: auto;
            border-radius: 10px;
            box-sizing: border-box;
            box-shadow: 0 20px 34px lime;

                height: auto;

        @media only screen and (max-width: 270px) {
            .child_div {
                width: 12rem;
                height: auto;
            }

            h4 {
                font-size: 18px;
            }
        }
    </style>
    <!-- css area start -->

</head>

<body>
    <div class="parent_div">
        <div class="child_div">
            <form action="registration_data" method="POST">
                <div
                    style="width: 100%;height:4rem;background-image: linear-gradient(to top, limegreen,green);border-radius:10px 10px 0px 0px; ">
                    <h4 class="text-center text-white pt-3">Registration Page</h4>
                </div>
                <div style="padding:2rem;border-radius:0 0 10px 10px;">
                    <label for="name" class="success">First Name :</label>
                    <input type="text" name="name" class="form-control form-group" style="color: blue;">
                    <label for="name" class="success">Last Name :</label>
                    <input type="text" name="name" class="form-control form-group" style="color: blue;">
                    <label for="name" class="success">Date of Birth :</label>
                    <input type="date" name="name" class="form-control form-group" style="color: blue;">
                    <label for="name" class="success">Email :</label>
                    <input type="text" name="email" class="form-control form-group" style="color: blue;">
                    <label for="name" class="success">Password :</label>
                    <input type="password" name="password" class="form-control form-group" style="color: orange;">
                    <label for="name" class="success">Confirm Password :</label>

                    <input type="submit" value="Signup" class="btn btn-success form-control form-group">
                </div>
        </div>
    </div>
    </form>
</body>

</html>

 

Output

js

 

Step 2 –Add below code in place of password <input/> tag

Now we need to add below code in place of password input tag because we need to add eyes font awesome using which we can show and hide password field using javascipt.

<label for="name" class="success">Password :</label>

<div style="position:relative; display:flex;"><input type="password" name="password" class="form-control form-group"
        id="myInput" style="color: orange;"><i class="far fa-eye" id="myInputss" onclick="myFunction()"
        style="position:absolute;left:92%; top:22%; display:block"></i><i class="fas fa-eye-slash" id="myInputs"
        style="display:none;position:absolute;left:92%; top:22%;" onclick="myFunction()"></i>
</div>

 

Now your form look like – 

js

 

Step 3 – Add below javascript inside <body> tag.

Now add below javascript inside body tag where all your form code is ended.

 <script>
    // show and hide password start
function myFunction() {
  var x = document.getElementById("myInput");
  if (x.type === "password") {
    x.type = "text";
  } else {
    x.type = "password";
  }
  var x = document.getElementById("myInputs"); 
  if (x.style.display === "none") { 
    x.style.display = "block";
  } else {
    x.style.display = "none";
  }
  var x = document.getElementById("myInputss"); 
  if (x.style.display === "block") { 
    x.style.display = "none";
  } else {
    x.style.display = "block";
  }
}
// show and hide password start
</script> 

 

Now All steps are completed and you can use below code ( all codes of above steps are combined in below code)  using which we can Toggle Password Visibility Using JavaScript or show/hide password field with eye icons using javascript.
