You should be enqueueing them in your functions.php
function font_scripts() {
wp_enqueue_style('montserrat', 'https://fonts.googleapis.com/css?family=Montserrat:400,700&display=swap');
}
add_action( 'wp_enqueue_scripts', 'font_scripts' );
What does is change exactly?
I actually wrote that code into my function.php but the number of css didnt change. do i need to change the font in my brooklyn theme to “theme font” instead of “google font”?
