Child theme CSS is not prioritized

Hi!

I’m building a childtheme and but my css does not work, only if I use !important; on every single line.

How can I change it?

add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
function my_theme_enqueue_styles() {
    $parenthandle = 'twenty-twenty-one-style'; // This is 'twenty-twenty-one-style' for the Twenty Twenty-one theme.
    $theme = wp_get_theme();
    wp_enqueue_style( $parenthandle, get_template_directory_uri() . '/style.css', 
        array(),  // if the parent theme code has a dependency, copy it to here
        $theme->parent()->get('Version')
    );
    wp_enqueue_style( 'custom-style', get_stylesheet_uri(),
        array( $parenthandle ),
        $theme->get('Version') // this only works if you have Version in the style header
    );
}
