I have a navbar at the top of my SharePoint Online sites. Each site has the same navigation structure, achieved using
terms. However, the size of the text is annoyingly small given that it functions as the only inter-site navigation menu.
I can write the CSS to modify these quite easily, but I'd be happy to apply a different "Look and Feel" template, but none of the templates provided affect the navbar.
My questions are:
How can I apply this CSS in SharePoint Online (rather than SharePoint on-prem)?
Is it possible to apply the same styling across many sites with the CSS referenced in one place?
I am designing these sites by clicking "Create Site" and using the in-browser editor, rather than using SharePoint Designer.
