can we apply the H2 text below the title -- ON ALL PAGES?

like this example-good
https://dev.miusa.org/miusas-disability-inclusion-consulting/


do it here
https://dev.miusa.org/eddi/

note- all top nav pages to change to that sub-text below the main header style
eg https://dev.miusa.org/our-work/

Is it easy to fix that?
