I tried to find the answers myself but with no luck so far.
When I look at the phone view it shows content that doesn’t appear in the larger device views. Previously it showed the same content but in a different order with images from the top of the page moved to the bottom, etc. I’m confused by what’s going on. The same thing happens when I reduce the width of the browser window so it’s not just the viewer, it’s really the website.

I’m very confused about text formatting. I know that there are classes but I don’t see where to apply different classes or to modify the classes. I tried adding a new section to a page and including text but the formatting doesn’t match the rest of the page. Is there a tutorial on how to work with text?
On the same page as above, if you squeeze it down to one column you see a section “Aerial Photos and Video”. How can I apply the same classes that the rest of the page uses? Also, I would like to reduce the line spacing, I think it looks too far apart. How can I modify the class to make this or other changes? Maybe I should just create a new class. How would I do that?
Can you recommend up to date tutorials? I have found several but most are at least a few years old…
Thank you for your patience with this wordpress and X theme beginner
