子主题functions.php不加入样式表

Question

paragraph.css样式不显示，尽管子主题style.css中的样式显示。

<?php 
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles');
function my_theme_enqueue_styles() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css');
    wp_enqueue_style( 'child-style',
        get_stylesheet_directory_uri() . '/style.css',
        array('parent-style'),
        wp_get_theme()->get('Version')
    ); 
    wp_enqueue_style( 'child-style',
        get_stylesheet_directory_uri() . '/paragraph.css',
        array('parent-style'),
        wp_get_theme()->get('Version')
    );
}
