What are some best practices for handling multiple CSS styles and classes in a PHP project?

When working on a PHP project that involves multiple CSS styles and classes, it's important to keep your code organized and maintainable. One best practice is to separate your CSS styles into different files based on their functionality or component. Another best practice is to use meaningful class names and avoid inline styles whenever possible. Lastly, consider using a CSS preprocessor like Sass or Less to help manage and organize your styles more efficiently.

<?php
// Example of separating CSS styles into different files
echo '<link rel="stylesheet" type="text/css" href="styles/main.css">';
echo '<link rel="stylesheet" type="text/css" href="styles/buttons.css">';
echo '<link rel="stylesheet" type="text/css" href="styles/forms.css">';
?>
