Hi Mike,
Thanks for your reply. I initially tried to imitate mobile by shrinking the browser window – and that does what I want. However, I get a different result on my phone(s). I don’t know how to clear the cache on a cell phone browser, but I did check on another phone that I hadn’t used before and got the same result (both iPhones using Safari). I’m attaching the screenshot here. This is what I see when the page first loads: http://www.drweitz.com/wp-content/uploads/2017/07/IMG_1955.png
