Unlock Hidden Power: 6 Little-Known Ways to Master Custom Block Styles in WordPress

Due to a bug, you need to add the style.css to the frontend. It doesn’t seem to be automatically loaded. You use wp_enqueue_style() and then use the hook wp_enqueue_scripts.
Then you’d add the following to your functions.php or plugin file:
function enqueue_theme_styles() {
wp_enqueue_style(
'my-theme-styles',
get_stylesheet_uri(), // This gets your style.css
array(),
wp_get_theme()->get( 'Version' )
);
}
add_action( 'wp_enqueue_scripts', 'enqueue_theme_styles' );
You also need to add style.css to the block editor so your users can see how the block style looks when they are working on the post or page.
