Show and Hide Password using Javascript

Show and Hide Password is a JavaScript project that is currently widely used. This allows you to hide the password or text in an input box.

 Currently, we see such systems in almost all types of social media and website login forms. Even when we turn on the window, we see the Show and Hide Password option in the Password Input Place.

 In this article, we are going to learn how to create a Show and Hide password system using JavaScript programming code. This type of system is used in a variety of login and registration forms. Earlier I designed many types of login forms but did not add the option to hide passwords and show. But in this article, I have shown that.

This type of design is used where passwords are input. When you input the password, it is seen in bullet format. In that place, you will see a small button or icon which, when clicked, will turn the bullet marks into characters.

Video Tutorial of Show and Hide Password

 If you have difficulty understanding then you can watch the video tutorial below. In the video tutorial below you will learn how I made this design very easily using JavaScript code.




Hopefully, the video tutorial above has helped you to know how I made this design. As you can see in the video above, I made a small box on the first web page. 

In that box, I created an input place to input. If you input a password in the input field, it will appear in bullet format. When you click on the icon to the right of that place, those bullet formats will become characters. When you click on that icon again, the passwords will be converted to bullet format again.

Show and Hide Password using Javascript [Source Code]

 For your convenience, I have given below the necessary source code. If you want, you can copy those codes and use them in your own project. First of all, you create an HTML and CSS file.

 Be sure to attach your CSS file to the HTML file. In this case, you must add the font awesome CDN link in the head section of your HTML file to implement the icon I used.

Use HTML code to build its structure

The following programming codes are the HTML programming codes that helped build the structure of this design. You copy the following HTML code and then paste it into the body tag (<body> </body>) of your HTML file.

HTML Code

 <!DOCTYPE html>
<!-- Design by rajtemplate.com -->
<html>
<head>
<!--font awesome icon cdn link-->
<link rel='stylesheet' href='https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.6.3/css/font-awesome.min.css'>
 
<link rel="stylesheet" href="css.css">
</head>
<body>
<div class="container">
  
  <div class="second">
   <input class="active" type="password" id="pass">
   <div class="group2">
    <i id="icon" class="fa fa-eye-slash"></i>
   </div>
  </div>
  
</div>
<script src="javascript.js"></script>
</body>
</html>



Design it using CSS code

Now let's design the HTML code added above using CSS code. For this, you copy the following CSS codes then paste them into your CSS file. If you do not create a CSS file, you can paste these codes into the HTML file using the style tag.


CSS Code

* {
 margin: 0;
 padding: 0;
 box-sizing: border-box
}

body {
 background: #1da1f2;  /* webpage background color */
}

.container {
 width: 340px;    /* box width */
 height: 90px;
 background: #fff;  /* box background color */
 border-radius: 5px;
 margin: 30px auto 0;
 padding-top: 22px;
 border: 1px solid #c5c4c4;
}

.container>div {
 width: 100%;
 height: 25%;
 text-align: center
}
 
.container>div input[type='password'],
input[type='text'] {
 width: 88%;
 height: 45px;   /* input place height */
 background: white;
 font-family: sans-serif;
 border: 2px solid #1da1f2;  /* input border */
 outline: nfirst;
 border-radius: 3px;
 margin: 1px auto 0;
 padding: 5px 40px 5px 10px;
 display: block;
 font-size: 22px;
 color: black;
}
 
.container>div .group2 {
 padding-left: 70px;
 padding-top: 10px;
 font: 22px sans-serif;
 position: relative;
 display: block;
 height: 40px;
 text-align: left;
 top: 0;
 left: 0;
}

.container>div .group2>i {
 position: absolute;
 right: 32px;  /* icon position */
 bottom: 51px;
 cursor: pointer

}


Activate it using JavaScript code

JavaScript plays a vital role in implementing this program (Show and Hide Password using Javascript). In this case, very little JavaScript is used. You copy the JavaScript code below and paste it into your HTML file using the script tag (<script> </script>).


JavaScript Code

 

var inputPass = document.getElementById('pass'),
    icon = document.getElementById('icon');
 
   icon.onclick = function () {
 
     if(inputPass.className == 'active') {
        inputPass.setAttribute('type', 'text');
        icon.className = 'fa fa-eye';
       inputPass.className = '';
 
     } else {
        inputPass.setAttribute('type', 'password');
        icon.className = 'fa fa-eye-slash';
       inputPass.className = 'active';
    }
 
   }
  


 I hope you have made this Show and Hide Password system. If you want to know how it works then check out the demo below 👇👇👇

3D Image Slideshow using Only HTML and CSS

3D Image Slideshow is a type of image gallery that is currently used on a variety of websites. It helps to keep many types of images neatly arranged together. This not only enhances the beauty of the website but also user satisfaction.  I have already created many types of image sliders and image galleries but it is a little different. Basically, we use JQuery or JavaScript to change the image in other designs. However, I did not use any JavaScript in this case. In this case, I made it using only HTML and css3 . Yeah Al that sounds pretty crap to me, Looks like css3 just got used to the modern animation effect .  In this case, no button was created to change the image. It tends to change from time to time by itself. This means that it is an automatic 3d image slider built with HTML and CSS code only. This 3D image slider is like a square box. At certain intervals, this box rotates from right to left. I have used four images around this box. When the box is rotated, e...
