Problem loading .css

Hi veryone!

Im developing a site on local with a child theme and in my child’s theme functions.php i got it registered

function avada_child_scripts() {
wp_enqueue_style( 'avada-child-stylesheet', get_template_directory_uri() . '/style.css', array());
}

add_action('wp_enqueue_scripts', 'avada_child_scripts');

So far so good, problem starts when i try to rename the css to style_es.css
the page doesnt load child’s css (I’ve changed from /style.css to /style_es.css inside the function.php)

My objetive is loading diffferent css depending on web language so im assuming that the code should be this one:

function avada_child_languages_scripts() {
	if ( ICL_LANGUAGE_CODE=='es' ) {
		wp_enqueue_style( 'avada-child-stylesheet', get_template_directory_uri() . '/style_es.css', array());
	} else{
		wp_enqueue_style( 'avada-child-stylesheet', get_template_directory_uri() . '/style_en.css', array());
	}

}
add_action('wp_enqueue_scripts', 'avada_child_languages_scripts');

Also this is what i got on child css
/*
Theme Name: Avada Child
Description: My style sheet
Author:Me
Template: Avada
*/

But it isnt working , what am i doing wrong?

thx everyone 🙂
