What are the alternatives to using frames in PHP for creating a layout where one section remains fixed while another section can be scrolled independently?

Using CSS position fixed and overflow properties can help achieve the desired layout where one section remains fixed while another section can be scrolled independently. By setting the position property of the fixed section to fixed and using overflow-y property on the scrollable section, we can create a layout similar to frames without using frames.

<!DOCTYPE html>
<html>
<head>
<style>
    .fixed {
        position: fixed;
        top: 0;
        left: 0;
        width: 100%;
        background-color: #333;
        color: #fff;
        padding: 10px;
    }

    .scrollable {
        margin-top: 50px;
        height: 500px;
        overflow-y: scroll;
        padding: 10px;
    }
</style>
</head>
<body>

<div class="fixed">
    Fixed Section
</div>

<div class="scrollable">
    <?php
    // Your PHP code for generating content in the scrollable section
    ?>
</div>

</body>
</html>
