The topic "HTML5 Features - Email Inputs" highlights a useful addition in HTML5 that simplifies collecting and validating email addresses in forms. The email input type ensures that the user enters a properly formatted email address, improving user experience and reducing errors.
Explanation
HTML5 introduced the <input type="email"> element specifically for email address entry. This element provides built-in validation to check if the input is in a standard email format (e.g., username@example.com).
Example
Here’s a basic implementation of an email input field:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Email Input Example</title>
</head>
<body>
<h1>Subscribe to Our Newsletter</h1>
<form action="/subscribe" method="post">
<label for="email">Email Address:</label>
<input type="email" id="email" name="email" placeholder="Enter your email" required>
<button type="submit">Subscribe</button>
</form>
</body>
</html>
Key Features of input type="email":
You can combine input type="email" with the pattern attribute for custom validation:
<input type="email" name="email" pattern="[a-z0-9._%+-]+@mydomain\.com" title="Please enter an email address from mydomain.com">
This ensures that only emails from a specific domain (e.g., mydomain.com) are accepted.

Key Features of input type="email":
- Automatic Validation: Browsers automatically verify if the input matches the standard email format.
- Error Handling: If the input is invalid, the browser displays an error message before form submission.
- Mobile-Friendly Keyboards: On mobile devices, email inputs display a specialized keyboard for typing email addresses (including @ and . symbols).
- Custom Messages: Developers can use the title attribute or JavaScript to customize validation messages.
