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 that a user can enter 
more than one value in 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-multiple-demo.php"><!-- Specifies the URL where the form data will be sent upon submission -->
  Select images: <input type="file" <!-- Creates an input field of type "file" for selecting files -->
name="my_image" multiple><!-- Sets the name attribute of the input field to "my_image" and allows multiple files to be selected -->
<input type="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's an <input> element with type "file", allowing users to select files from their device. The name attribute is set to "my_image" to identify the input data on the server side. The multiple attribute allows users to select more than one file.
Finally, an <input> element with type "submit" is used to create a submit button within the form, allowing users to submit the form data.
