What are the advantages and disadvantages of using inline CSS versus adding classes dynamically in JavaScript for styling elements in a PHP application?

When styling elements in a PHP application, using inline CSS can provide a quick and easy way to apply styles directly to individual elements. However, this approach can lead to messy and hard-to-maintain code, as the styles are mixed in with the HTML markup. On the other hand, adding classes dynamically in JavaScript allows for better separation of concerns and more organized code, but it may require additional scripting and can be less performant than inline CSS. 

<?php
// Using inline CSS to style an element
echo '<div style="color: red; font-size: 16px;">Hello, World!</div>';

// Adding classes dynamically in JavaScript to style an element
echo '<div id="styledElement">Hello, World!</div>';
echo '<script>';
echo 'document.getElementById("styledElement").classList.add("redText", "largeFont");';
echo '</script>';
?>
