What is the difference between including content with PHP and using frames in terms of background color?

When including content with PHP, the background color is consistent throughout the entire page because the content is dynamically generated within the same HTML document. On the other hand, using frames allows for different sections of the webpage to have separate background colors, which can create a disjointed look. To ensure a consistent background color when including content with PHP, you can set the background color in the main HTML document that includes the PHP content.

<!DOCTYPE html>
<html>
<head>
    <title>Page Title</title>
    <style>
        body {
            background-color: #f0f0f0; /* Set the background color for the entire page */
        }
    </style>
</head>
<body>
    <?php
        // PHP code to include content here
    ?>
</body>
</html>
