How can the use of display:none affect the usability of a PHP application without JavaScript?

Using display:none can affect the usability of a PHP application without JavaScript because it hides elements from the user interface, making them inaccessible. To maintain usability, it's better to use PHP to conditionally render elements based on user input or application logic.

<?php
// Example of conditionally showing content in PHP without using display:none

$showContent = true; // Set this variable based on application logic or user input

if ($showContent) {
    echo "<div>This content is displayed</div>";
}
?>
