Introduction:
In today’s tutorial, we will learn how to create an interactive password strength meter using HTML, CSS, and JavaScript. This project will not only enhance your web development skills but also provide a practical and visually appealing user experience. We’ll guide you through each step, and you can also watch the video tutorial on our YouTube channel for a visual walkthrough.
Things You Will Learn:
By following this tutorial, you will gain knowledge and experience in the following areas:
- HTML: You’ll create the structure of the password strength meter interface using HTML.
- CSS: You’ll style the HTML elements to make the meter visually engaging.
- JavaScript: You’ll implement the logic for the password strength meter to update dynamically as the user types.
Video Tutorial:
Here is the video tutorial for this project. If you like the tutorial subscribe to my YouTube channel. I post new projects based on HTML, CSS, and Javascript on my channel regularly.
Project Folder Structure:
Before we start coding we take a look at the project folder structure. We start by creating a folder called – ”Password Strength Background”. Inside this folder, we have 3 files. These files are :
- index.html
- style.css
- script.js
- background image
HTML:
We begin with the HTML code. Copy the code below and paste it into your HTML document.
<!DOCTYPE html>
<html lang="en">
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Password Strength Background</title>
<!-- Google Fonts -->
<link
href="https://fonts.googleapis.com/css2?family=Poppins:wght@400;600&display=swap"
rel="stylesheet"
/>
<!-- Stylesheet -->
<link rel="stylesheet" href="style.css" />
</head>
<body>
<div class="background" id="background"></div>
<div class="input-container">
<h1>Image Password Strength</h1>
<div class="input-box">
<label for="password">Password</label>
<input type="password" id="password" placeholder="Enter Password" />
</div>
</div>
<!-- Script -->
<script src="script.js"></script>
</body>
</html>
CSS:
Next, we style our code using CSS. For this copy, the code provided to you below and paste it into your stylesheet.
body {
margin: 0;
padding: 0;
font-family: "Poppins", sans-serif;
overflow: hidden;
}
.input-container {
display: flex;
flex-direction: column;
place-items: center;
background-color: #ffffff;
width: min(90%, 500px);
position: absolute;
transform: translate(-50%, -50%);
padding: 3em 0;
top: 50%;
left: 50%;
border-radius: 1em;
}
input {
border: 1px solid black;
padding: 0.5em;
border-radius: 0.2em;
}
.background {
background: url(sunflowers-bg.jpg) no-repeat center;
background-size: cover;
height: 100vh;
width: 100vw;
position: absolute;
z-index: -1;
filter: blur(30px);
}
JS:
Finally, we add functionality using Javascript. For this once again copy the code below and paste it into your script file.
const password = document.getElementById("password");
const background = document.getElementById("background");
password.addEventListener("input", () => {
const input = password.value;
const blurValue = 16 - input.length;
background.style.filter = `blur(${blurValue}px)`;
});
Conclusion:
Congratulations! You’ve successfully created an interactive password strength meter using HTML, CSS, and JavaScript. Users can now see the background blur change as they type their password, giving them a visual indicator of their password’s strength.
