If I wanted to change a Moodle graphic icon and I am using Boost theme how do I overwrite that? I understand creating a child theme etc is the proper way to go. But I am just interested in changing the Boost theme specific fontawesome icon to test it out quickly and simply. Of course the Boost theme config.php file shows $THEME->iconsystem = \core\output\icon_system::FONTAWESOME; I have read the documentation but I am not really understanding how to effect this change in the code. Also when I put for example
class="far fa-user"></I> in the mustache the image is broken in the user/browser view. So I'm not understanding how to modify a theme in this regard. Thanks in advance for pointers!
