Is it recommended to use HTML tags like <small> for styling in PHP applications, or should CSS be preferred?

It is generally recommended to use CSS for styling in PHP applications rather than HTML tags like <small>. This is because CSS allows for better separation of concerns, making it easier to maintain and update the styling of your application. By using CSS, you can apply styles consistently across your entire application and easily make changes without having to modify each individual HTML tag.

echo '<div style="font-size: small;">This text will be styled smaller using inline CSS.</div>';
