Solution:

HTML Code:

<!DOCTYPE html><!-- Declares the document type as HTML -->
<html><!-- Root element of the HTML document -->
<head><!-- Contains metadata about the HTML document -->
<title>How spread the size of shadow</title><!-- Sets the title of the HTML document -->
<style type="text/css"> /* Begins a CSS style block */
div { /* Defines a CSS rule for all div elements */
width: 200px; /* Sets the width of the div element to 200 pixels */
height: 100px; /* Sets the height of the div element to 100 pixels */
border: 3px solid #FF0000; /* Sets the border properties of the div element */
background-color: #4364FF; /* Sets the background color of the div element to a shade of blue */
box-shadow: 40px 40px 40px 5px yellow; /* Sets the shadow effect for the div element with a horizontal offset of 40 pixels, vertical offset of 40 pixels, blur radius of 40 pixels, spread radius of 5 pixels, and yellow color */
}
</style><!-- Ends the CSS style block -->
</head><!-- Ends the head section of the HTML document -->
<body><!-- Contains the content of the HTML document -->
<p>w3resource Tutorial</p><!-- Displays a paragraph with the text "w3resource Tutorial" -->
<div>Box-shadow spread</div><!-- Displays a div element with the text "Box-shadow spread" and a shadow with spread effect -->
</body><!-- Ends the body section of the HTML document -->
</html><!-- Ends the HTML document -->
