Let’s create an Animated Credit Card using HTML, CSS, and JavaScript! 💳✨ This interactive project mimics a real credit card that flips and updates live as users enter card details – perfect for practicing UI/UX and animation skills.
We’ll use:
- HTML to structure the front and back of the credit card.
- CSS for stylish design, layout, and smooth flip animations.
- JavaScript to dynamically update the card number, name, expiry, and CVV in real time.
Whether you’re new to web development or want to sharpen your interactive UI skills, this project is a fun and modern way to learn!
HTML :
This HTML code builds a responsive, animated credit card form using Vue.js. It visually displays a credit card that updates in real time as the user fills out fields like card number, holder name, expiry date, and CVV. The card flips to the back when the CVV field is focused. It uses custom styles, Vue transitions for smooth animations, and input masks (vue-the-mask) for proper formatting. The card design also changes based on the card type (Visa, MasterCard, etc.), and a randomly selected background image is used to style the card’s appearance.

CSS :
This CSS code styles a credit card form interface with a modern, responsive design. It uses Google Fonts and a dark background theme, styles the form container with padding, shadows, and rounded corners, and handles responsive layouts for mobile devices. It also designs a realistic-looking credit card with flip animations for front and back, input fields with focus effects, and transitions for animations. Overall, it creates a visually rich, animated UI for entering and displaying credit card details.

}JavaScript:
This Vue.js code creates an interactive credit card form. It manages data like card number, name, expiry, and CVV, and updates the card design based on the card type (Visa, MasterCard, etc.). When the component mounts, it focuses on the card number input. It also handles flipping the card for CVV input, shows the input highlight dynamically, and ensures valid month/year selection. The card number format adjusts based on the detected card type using regex checks.
