Steps to change password visibility on just image click.


Step 1: Add basic html structure and boxes.

Create box or house for input field and image 


HTML


<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>
    <link rel="stylesheet" href="index.css">
</head>
<body>

    <div class="container">
        <div class="box">


        </div>
    </div>
    
</body>
</html>

CSS


*{
    padding: 0;
    margin: 0;
}
.container{
    width: 100%;
    height: 100vh;
    background-color: #000;
    display: flex;
    justify-content: center;
    align-items: center;
}
.box{
    width: 350px;
    background-color: #fff;
    padding: 20px 25px;
}

Output :


show and hide password with image


Step 2: Add input field and image.

Add input field and image inside above created box. 

As we have to change the visibility of password based on image click. We'll call a function named change() on click of the image. You can also do it with javascript. But any way we've just call it, Later we'll declare the function inside the javascript.


HTML


	<div class="input_box">
    <input type="text" class="input" placeholder="Password">
    <img src="images/hide.png" onclick="change()" class="password">
</div>

CSS


.password{
    width: 40px;
    height: auto;
    cursor: pointer;
}
.input_box{
    width: 100%;
    border-width: 0px 0px 2px 0px;
    border-style: solid;
    display: flex;
    align-items: center;
}
.input{
    border: none;
    outline: none;
    width: 100%;
    font-size: 25px;
    padding: 8px 0px;
}

Output : 


show and hide password with image


Step 3: Create JavaScript Function to Show and Hide Password.

Now let's declare the function that we called above inside the image tag on click.


In that function we'll check, if input type is text or not. If input type is text we'll change it to password and also change image of img tag.

And else if input type is not text then we'll change input type to text and also change image of img tag too.

is image folder and image name (like this password.src = folder of image/image name).

JavaScript


	let input = document.querySelector('.input');
    let password = document.querySelector('.password');

    function change(){
        if (input.type == 'text') {
            input.type = 'password';
            password.src = 'images/visible.png';
        }else{
            input.type = 'text';
            password.src = 'images/hide.png';
        }
    }


As you can see in above code, their is an password.src = images/hide.png. Here's in images/hide.png,  images is folder in which hide.png image stored.

Output :

when click on img tag or class name "password".
