    margin: 50px auto;
    padding: 20px;
    background: #fff;
    border-radius: 10px;
    box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1);
}

JavaScript Code:

javascriptCopy codedocument.getElementById('calculateBtn').addEventListener('click', function () {
    const amount = parseFloat(document.getElementById('amount').value);
    const gstRate = parseFloat(document.getElementById('gstRate').value);

    if (isNaN(amount) || amount <= 0) {
        alert('Please enter a valid amount.');
        return;
    }

    const gstAmount = (amount * gstRate) / 100;
    const totalAmount = amount + gstAmount;

    document.getElementById('gstAmount').textContent = gstAmount.toFixed(2);
    document.getElementById('totalAmount').textContent = totalAmount.toFixed(2);
});
