<style type="text/css">
/* CSS styles start here */

</style>
</head>
<body>
<div class="container"><!-- Create a container div for content -->
	<p>CSS3 <em>calc</em> example</p><!-- Add a paragraph with emphasized text inside the container -->
</div>
</body>
</html>

Explanation:

This HTML code demonstrates the use of CSS3's calc() function to calculate values.
In the CSS, the .container class is defined to style a container div.
The width property of the container is set using the calc() function, which subtracts 10% from 500px.
This allows for responsive design, where the container width adjusts dynamically based on the viewport size.
Other styles like background color, text color, text alignment, padding, and margin are applied to the container for visual appearance and layout.
Inside the container, there is a paragraph element with emphasized text, serving as an example content.
