What are the potential drawbacks of using frames to hide subpages on a website?

Using frames to hide subpages on a website can lead to issues with search engine optimization, as search engines may have difficulty indexing the content within the frames. Additionally, frames can cause problems with bookmarking and sharing specific subpages, as the URL may not accurately reflect the content being viewed. It is recommended to use CSS and JavaScript to dynamically load content instead of relying on frames for hiding subpages. 

// Example PHP code for dynamically loading content using AJAX

<div id="content"></div>

<script>
    function loadPage(page) {
        var xhttp = new XMLHttpRequest();
        xhttp.onreadystatechange = function() {
            if (this.readyState == 4 && this.status == 200) {
                document.getElementById("content").innerHTML = this.responseText;
            }
        };
        xhttp.open("GET", page, true);
        xhttp.send();
    }

    // Example usage
    loadPage("subpage1.php");
</script>
