I found code to immediately show CSS site changes on the frontend.
I have many times become very frustrated when I adjusted some CSS and could not immediately see the changes on the frontend. I have come across a technique that would skip the cache system and show the CSS changes right away.
Add the following to your functions.php file:
// Version CSS file in a theme wp_enqueue_style( 'theme-styles', get_stylesheet_directory_uri() . '/style.css', array(), filemtime( get_stylesheet_directory() . '/style.css' ) ); // Version JS file in a theme wp_enqueue_script( 'theme-scripts', get_stylesheet_directory_uri() . '/js/scripts.js', array(), filemtime( get_stylesheet_directory() . '/js/scripts.js' ) );
