<title>How to specify a short hint that describes the expected value of an input element</title><!-- Sets the title of the document -->
</head>
<body>
<form method="post" <!-- Begins a form element with the method attribute set to "post", indicating that form data will be submitted via HTTP POST method -->
action="https://www.w3resource.com/html-css-exercise/basic/solution/input-name-answer-demo.php"><!-- Specifies the URL where the form data will be sent upon submission -->
<input type="text" name="fullname" <!-- Creates a text input field for entering the user's full name. The name attribute is set to "fullname" to identify the input data on the server side -->
placeholder="Full Name"><br><!-- Provides a short hint or placeholder text inside the input field, indicating the expected value (Full Name) -->
<input type="text" name="address" <!-- Creates a text input field for entering the user's address. The name attribute is set to "address" to identify the input data on the server side -->
placeholder="Address"><br><!-- Provides a short hint or placeholder text inside the input field, indicating the expected value (Address) -->
<input type="submit" value="Submit"><!-- Creates a submit button within the form -->
</form>
</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>).
Within the <body> section, a <form> element is used to create a form for user input. The method attribute is set to "post", indicating that form data will be submitted via HTTP POST method, and the action attribute specifies the URL where the form data will be sent upon submission.
Inside the form, there are two <input> elements with type "text" for entering the user's full name and address. The name attributes are set to "fullname" and "address" respectively to identify the input data on the server side.
The input elements include a placeholder attribute, which provides a short hint or placeholder text inside the input field, indicating the expected value. In this case, "Full Name" and "Address" are provided as hints for the respective input fields.
Finally, an <input> element with type "submit" is used to create a submit button within the form, allowing users to submit the form data.
