<title>How to specify that a keygen element should automatically get focus when the page loads</title><!-- Sets the title of the document -->

Name: <input type="text" name="name"><!-- Creates a text input field for entering the name. The name attribute is set to "name" to identify the input data on the server side -->
Encryption: <keygen name="security" autofocus><!-- Creates a key-pair generator field for encryption with autofocus attribute, which specifies that the keygen element should automatically get focus when the page loads -->
<input type="submit"><!-- Creates a submit button within the form -->
</form><!-- Ends the form element -->
</body>
</html>

Explanation:

The HTML document starts with a declaration of its type and version (<!DOCTYPE html>).
The <html> element encloses the entire HTML document.
The <head> section contains metadata about the document, including the character encoding (<meta charset="utf-8">) and the title of the document (<title>).
Inside the <body> section, there's a <form> element, which creates a form for user input. The method attribute is set to "post", indicating that form data will be submitted via HTTP POST method. The action attribute specifies the URL where the form data will be sent upon submission.
Within the form, there are two input fields:

<input type="text">: Creates a text input field for entering the name. The name attribute is set to "name" to identify the input data on the server side.
<keygen>: Creates a key-pair generator field for encryption. The name attribute is set to "security" to identify the input data on the server side. The autofocus attribute is added to specify that the keygen element should automatically get focus when the page loads.
