The styles are defined inside the file theme.json and you can use a code editor as Visual Studio Code to edit it.

First, I recommend you to dig some basic lessons from Carolina Nymark here: https://fullsiteediting.com/lessons/global-styles/

Good luck!

Use the plugin Create Block Theme to generate your child theme.
Inside your child theme create a functions.php file and paste the following code:

`<?php
// Enqueue styles from parent theme
function add_style() {
wp_enqueue_style( ‘style’, get_stylesheet_uri() );
}

You can use:

/* Code in header */
add_action('wp_head', 'code_header');
function code_header(){
?>
YOUR CODE HERE
<?php
};
