I wrote a small plugin and i want to add some css design my plugin meta boxes in the WordPress system. All the scripts of adding a css file to WordPress plugin that I found are referring to including a css file in the plugin output page on the website itself. - wp_enqueue_scripts
the solution i created is to use this piece of code in my plugin page:
echo '<style type="text/css">';
include( '/css/style.css' );
echo '</style>';
But if feels to me like an unprofessional solution so I wanted to ask if anyone knows a better solution
