    How to make Animated WiFi Card Generator using HTML CSS and JavaScript

    Coding StellaBy No Comments7 Mins Read

    Let’s create a beautiful “WiFi QR Card Generator” using HTML, CSS, and JavaScript. It will feature a stylish WiFi login card with an animated QR scanner, modern colors, smooth animations, and a print option.

    We’ll use:

    • HTML to create the WiFi card structure, including the Network Name, Password fields, QR code, connection message, and print button.
    • CSS to design the card with a modern orange background, bold borders, shadows, responsive layout, and animations like the moving QR scanner and floating icon.
    • JavaScript to generate the WiFi QR code automatically using the entered network name and password, update the QR code whenever the user types, add a small bounce animation, and open the print option when the button is clicked.

    The QR code automatically changes whenever the user enters or updates the WiFi name or password. The animated scanner gives the QR code a more interactive look, while the print feature allows the user to easily print the WiFi card.

    This project is a simple and practical way to learn how HTML, CSS, and JavaScript work together to create a useful, responsive, animated, and interactive WiFi QR code generator.

    HTML :

    HTML is used to create the structure of the WiFi card. It creates the heading “WiFi Login”, the QR code area, input boxes for the Network Name (SSID) and Password, the “Connect Instantly” message, and the Print WiFi Card button. It also connects the CSS file using <link> and the JavaScript file using <script>. In simple words, HTML decides what elements are present on the webpage.

      </label>
    </div>

  <div class="scan-notice">

    </div>
  </div>

  <button type="button">Print WiFi Card</button>
</form>
  <script src="./script.js"></script>
</body>
</html>

    CSS :

    CSS is used to design and style the WiFi card. It gives the page the orange animated grid background, white card, borders, shadows, colors, fonts, rounded corners, and spacing. It also creates animations such as the QR code scanner moving up and down, the card appearing from the bottom, and the phone icon floating. The @media sections make the design responsive on mobile and change the appearance when printing. In simple words, CSS decides how the webpage looks and how it is animated.

    JavaScript:

    JavaScript is used to make the WiFi card interactive and functional. It takes the Network Name and Password entered by the user and creates the WiFi information in the format required for a QR code. Whenever the user types something, JavaScript updates the QR code using the QR Server API. It also adds a small bounce effect to the QR code whenever the user types. Finally, when the user clicks Print WiFi Card, JavaScript opens the browser’s print option using window.print(). In simple words, JavaScript makes the webpage work and respond to user actions.

    const img = document.querySelector('img');
const ssid = document.querySelector('.ssid');
const password = document.querySelector('.password');
const button = document.querySelector('button');
const qrContainer = document.querySelector('.qr-container');

function update() {
  const wifi = `WIFI:T:WPA;S:${ssid.value};P:${password.value};;`;
  img.src = `https://api.qrserver.com/v1/create-qr-code/?size=164x164&data=${encodeURIComponent(wifi)}`;
  
  // Interactive bounce animation when typing
  qrContainer.style.transform = 'scale(0.92)';
  setTimeout(() => {
    qrContainer.style.transform = 'scale(1)';
  }, 150);
}

ssid.addEventListener('input', update);
password.addEventListener('input', update);

button.addEventListener('click', () => {
  window.print();
});

    In this project, we created a beautiful “I Love You” 3D Heart Animation using HTML, CSS, and JavaScript. HTML provided the canvas, CSS created the dark background and responsive layout, while JavaScript handled the heart shape, text, 3D rotation, and smooth animation. This project shows how simple web technologies can be combined to create creative and engaging visual effects.

    This project is a simple and practical way to understand how HTML, CSS, and JavaScript work together to create an interactive and visually engaging web interface.
