Are there any potential pitfalls when using iframes or div with style="overflow: scroll;" for scrollbars in PHP pages?

Using iframes or divs with style="overflow: scroll;" for scrollbars in PHP pages can potentially cause issues with responsiveness and accessibility. It is important to ensure that the content within the iframe or div is properly sized and responsive to different screen sizes. Additionally, using iframes can impact SEO as search engines may not be able to crawl content within iframes.

        <?php
            // PHP code to generate scrollable content
            for ($i = 1; $i <= 50; $i++) {
                echo "<p>Scrollable content item $i</p>";
            }
