In this article, we will discuss the solution for the Interactive Credit Card Details Form – Frontend Mentor Challenge #tsbsankara. This challenge involves creating a credit card details form with interactive features using HTML, CSS, and JavaScript.

The HTML structure for the credit card details form is quite simple. It consists of a container div that holds the form elements. Inside the form, there are input fields for the card number, card holder name, expiry date, and CVV. The form also includes a submit button for users to submit their credit card details.

“`css
.container {
max-width: 400px;
margin: 0 auto;
padding: 20px;
border: 1px solid #ccc;
border-radius: 5px;
}

.form-group {
margin-bottom: 20px;
}

label {
display: block;
margin-bottom: 5px;
}

input {
width: 100%;
padding: 10px;
border: 1px solid #ccc;
border-radius: 5px;
box-sizing: border-box;
}

button {
padding: 10px 20px;
background-color: #007bff;
color: #fff;
border: none;
border-radius: 5px;
cursor: pointer;
}
“`

For the CSS styling, we have defined the container to have a maximum width of 400px with some padding and border to give it a neat appearance. The input fields and buttons are styled with padding, border, and border-radius to make them more user-friendly.

“`javascript
document.getElementById(‘creditCardForm’).addEventListener(‘submit’, function(event) {
event.preventDefault();

let cardNumber = document.getElementById(‘cardNumber’).value;
let cardHolder = document.getElementById(‘cardHolder’).value;
let expiryDate = document.getElementById(‘expiryDate’).value;
let cvv = document.getElementById(‘cvv’).value;

// Perform validation and submission logic here
});
“`

For the JavaScript functionality, we have added an event listener to the form to capture the form submission event. Inside the event listener, we can access the values of the form inputs and perform any validation or submission logic as needed.

Overall, the Interactive Credit Card Details Form challenge is a great way to test your frontend development skills and improve your understanding of HTML, CSS, and JavaScript. By creating a user-friendly and interactive credit card details form, you can enhance the user experience and ensure that users can easily input their credit card details for online transactions.
