To restrict access to your website based on age, you can use HTML, CSS, and JavaScript to create an age verification gateway. Here's a basic example:

# Age Verification HTML Code
```
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Age Verification</title>
<style>
/* Add some basic styling to make it look decent */
body {
font-family: Arial, sans-serif;
text-align: center;
}

.age-verification-container {
width: 300px;
margin: 50px auto;
padding: 20px;
border: 1px solid #ccc;
border-radius: 10px;
box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);
}
</style>
</head>
<body>
<div class="age-verification-container">
<h2>Age Verification</h2>
<p>Please enter your birthdate to verify your age.</p>
<form id="age-verification-form">
<label for="birthdate">Birthdate:</label>
<input type="date" id="birthdate" name="birthdate" required>
<button type="submit">Verify Age</button>
</form>
<div id="age-verification-result"></div>
</div>

<script>
// Get the form and result elements
const form = document.getElementById('age-verification-form');
const resultElement = document.getElementById('age-verification-result');

// Add an event listener to the form submission
form.addEventListener('submit', (e) => {
e.preventDefault();

// Get the birthdate input value
const birthdateInput = document.getElementById('birthdate');
const birthdate = new Date(birthdateInput.value);

// Calculate the age
const age = calculateAge(birthdate);

// Check if the age is 18 or older
if (age >= 18) {
// If the age is valid, redirect to the website
resultElement.innerHTML = 'You are allowed to enter the website.';
// Replace this with your website's URL
window.location.href = 'https://example.com';
} else {
// If the age is not valid, display an error message
resultElement.innerHTML = 'You are not allowed to enter the website. You must be at least 18 years old.';
}
});

// Function to calculate the age
function calculateAge(birthdate) {
const today = new Date();
let age = today.getFullYear() - birthdate.getFullYear();
const monthDiff = today.getMonth() - birthdate.getMonth();
if (monthDiff < 0 || (monthDiff === 0 && today.getDate() < birthdate.getDate())) {
age--;
}
return age;
}
</script>
</body>
</html>
```

This code creates a basic age verification form that asks for the user's birthdate. When the form is submitted, it calculates the user's age and checks if it's 18 or older. If the age is valid, it redirects the user to the website. If the age is not valid, it displays an error message.

Please note that this is a basic example and may not be foolproof. Users can still bypass this verification by entering a fake birthdate. For a more robust age verification solution, you may want to consider using a third-party service or implementing additional verification steps.

Also, keep in mind that this code is for illustrative purposes only and should not be used in production without proper testing and validation.
