Solution:

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 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-form-answer-demo.php"><!-- Specifies the URL where the form data will be sent upon submission -->
  First Name: <input <!-- Creates a text input field for entering the first name. The name attribute is set to "fname" to identify the input data on the server side -->
type="text" name="fname"><br><!-- Provides a line break after the input field -->
  Address: <input type="text" <!-- Creates a text input field for entering the address. The name attribute is set to "address" to identify the input data on the server side -->
name="address"><br><!-- Provides a line break after the input field -->
<input type="image" <!-- Creates an image input field, which acts as a submit button -->
src="http://localhost/html-css-exercise/basic/solution/input-altimages.jpg" <!-- Specifies the URL of the image to be displayed as the submit button -->
alt="Submit" <!-- Specifies the alternate text for the image -->
width="80" <!-- Sets the width of the image to 80 pixels -->
height="60"><!-- Sets the height of the image to 60 pixels -->
</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's an <input> element with type "text" for entering the first name. The name attribute is set to "fname" to identify the input data on the server side.
Another <input> element with type "text" is used to create a text input field for entering the address. The name attribute is set to "address" to identify the input data on the server side.
Finally, an <input> element with type "image" is used to create an image input field, which acts as a submit button. The src attribute specifies the URL of the image to be displayed as the submit button, and the alt attribute provides alternate text for the image. The width and height attributes set the dimensions of the image to 80 pixels and 60 pixels respectively.
