Posts navigation appearance change

Hi there! This is a continuation of a topic I started on wordpress forum: https://wordpress.org/support/topic/next-page-button-6/
I can’t figure out how to send a dm here. I don’t know if anyone could help me out here? :’)
Or with an answer to my question in the link, regarding posts navigation.

Thank you!
