How can PHP and CSS be used together to replace frames for a better user experience?

Frames are outdated and can cause issues with usability and SEO. To replace frames for a better user experience, PHP can be used to include different content on a single page dynamically, while CSS can be used to style the layout. By using PHP to include different content based on user interactions or page requests, and CSS to style the layout, we can create a seamless user experience without the drawbacks of frames. 

<?php
// index.php
?>

<!DOCTYPE html>
<html>
<head>
    <title>Dynamic Content Example</title>
    <link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>

<div class="container">
    <div class="sidebar">
        <?php include 'sidebar.php'; ?>
    </div>
    <div class="content">
        <?php include 'content.php'; ?>
    </div>
</div>

</body>
</html>
