This is what I mean about the Mobile Usability issues warnings that I get from the Google Search Console:
So, obviously, Google doesn't know how to zoom in and out on a website, either?!!
The issue, for me, is not so much a CSS fix to increase the text size for existing site content. I can work with my moderator on that...
What I am more interested in is just making the default text size for any new content posted larger, so that we can at least see an end to this Herculean task.
