Thanks for your comment.
Tried the edit page in Opera. Same problem in Chrome and Opera.
Tried the JS trouble shooting errors, but I don’t know how to interpret the results or even if the results show an error.
The text is the error, if this is an error, is:
Consider using ‘dppx’ units, as in CSS ‘dpi’ means dots-per-CSS-inch, not dots-per-physical-inch, so does not correspond to the actual ‘dpi’ of a screen. In media query expression: print, not all, (-webkit-min-device-pixel-ratio: 1.25), (min-resolution: 120dpi)
It does not look anything like what an error looks like in this example.

The page is here.
If there is a problem that was introduced by a plugin, the site is new enough that I can delete the entire site and start over. It would be nice to know what happened so it can be avoided in the future. The error is one that started, perhaps after adding a plugin because this did not start until well after the page was created and published several days ago.
Whatever the problem, it affects all pages.
