Snippet

Hi @summitwinterguard,

I can’t see that text on your site, as I do not have an account, and so I’m not sure what CSS code I might use.

Thanks @summitwinterguard, though you might want to remove that information from this site.

This snippet should accomplish what you are looking for:

add_action( 'wp_head', function () { ?>
<style>

h3.user-heading {
    font-size: 15px;
}

h4.user-heading {
    font-size: 10px;
}

</style>
<?php } );
