Solution:

HTML Code:

<!doctype html><!-- Declares the document type and version of HTML -->
<html><!-- Opening tag for the HTML document -->
<head><!-- Opening tag for the head section which contains metadata -->
<title>HTML CSS Exercise - Style the element which is not empty</title><!-- Title of the HTML document -->
<style> /* Opening tag for CSS styling */
.container { /* Styles for elements with class 'container' */
background: #5ac4ed; /* Sets the background color to a shade of blue */
height: 150px; /* Sets the height of the container */
width: 200px; /* Sets the width of the container */
margin:10px; /* Sets the margin around the container */
}

.container:empty { /* Styles for empty elements with class 'container' */
background: #ec8007; /* Sets the background color to a shade of orange */
}
</style><!-- Closing tag for CSS styling -->
</head><!-- Closing tag for the head section -->
<body><!-- Opening tag for the body section which contains the content -->
<div class="container"><!-- I am empty --></div><!-- Empty container div with a comment -->
<div class="container">I am not empty</div><!-- Container div with text content -->
</body><!-- Closing tag for the body section -->
</html><!-- Closing tag for the HTML document -->

Explanation:

The HTML document consists of two <div> elements with the class 'container'.
The first <div> is empty, containing only a comment .
The second <div> contains text content "I am not empty".
CSS styling is applied within <style> tags.
The .container class sets the background color, height, width, and margin of the container.
The :empty pseudo-class selects elements that have no children (including text nodes), and applies a different background color to them.
