The code on the page just generates links to share the content/page to the relevant social network. There's no JavaScript or anything to talk to the network; each is just a dumb link like any other link on the screen.

The h3 tag can be changed with this filter: https://github.com/robincornett/scriptless-social-sharing/blob/develop/includes/output/class-scriptlesssocialsharing-output.php#L375, so you could make it strong instead of h3 quite easily, yes.

Here's an example snippet to add to your site: https://wordpress.org/support/topic/change-h3-to-p/#post-12102506

You can add the code to your theme's functions.php file (make a backup first), or use a plugin like WPCode to add snippets.
