<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Odd or Even Checker</title>
    <script>
        function checkOddOrEven() {
            // Step 1: Get the value from the input field
            const numberInput = document.getElementById("numberInput").value;
            const number = parseInt(numberInput);

            // Step 2: Validate input
            if (isNaN(number)) {
                document.getElementById("result").innerText = "Please enter a valid number.";
                return;
            }

            // Step 3: Determine if the number is odd or even
            if (number % 2 === 0) {
                document.getElementById("result").innerText = `${number} is an even number.`;
            } else {
                document.getElementById("result").innerText = `${number} is an odd number.`;
            }
