HTML Code:

<!DOCTYPE html><!-- Declares the document type and version of HTML -->
<html>
<head>
<meta charset="utf-8"><!-- Specifies the character encoding for the document -->
<title>How to specify the width, in characters, 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-size-answer-demo.php"><!-- Specifies the URL where the form data will be sent upon submission -->
  User Name: <input type="text" <!-- Creates a text input field for entering the user's name. The name attribute is set to "user_name" to identify the input data on the server side -->
name="user_name" size="15"><br><!-- Sets the width of the input field to accommodate 15 characters -->
  Password: <input type="text" <!-- Creates a text input field for entering the user's password. The name attribute is set to "password" to identify the input data on the server side -->
name="password" maxlength="8" <!-- Sets the maximum length of the input field to 8 characters -->
size="10"><br><!-- Sets the width of the input field to accommodate 10 characters -->
<input type="submit" <!-- Creates a submit button within the form -->
value="Submit"><!-- Sets the value of the submit button to "Submit" -->
</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 for entering the user's username and password. The name attributes are set to "user_name" and "password" respectively to identify the input data on the server side.
The input field for "User Name" has a size attribute set to "15", which specifies the width of the input field to accommodate 15 characters.
The input field for "Password" has a size attribute set to "10", which specifies the width of the input field to accommodate 10 characters. Additionally, it has a maxlength attribute set to "8", limiting the maximum length of the input to 8 characters.
Finally, an <input> element with type "submit" is used to create a submit button within the form, allowing users to submit the form data.
