Psink: thanks for responding. I don’t see the “masthead.wrapper” code you quote anywhere in my CSS code. I’ve copied the entire code below. Do you see it there?

Psink: I inserted that CSS and I now can see the menu on a mobile device again, which is great, but the featured image on a mobile device is still way too big for my phone’s display. Is there a fix for that?

I assumed the theme would automatically resize contents for different platforms. Is that not the case? Should I be using a jpg of a different size for a featured image?

Thanks.
David

Psink: that didn’t seem to affect the size of the featured image on my phone. It’s still way too big.

Doesn’t the theme have a way of automatically resizing for mobile devices?

Thanks.
David

Psink: I just realized, after looking at your screenshot, that we might be referring to different placements of the image. I’m referring to when you click in the main menu: “TICKETS AND RESERVATIONS FOR THE NOVEMBER 19 SUNDAY JAZZ SALON: THE ULYSSES OWENS, JR. QUARTET!”. When it goes to that page, it looks fine on my desktop, but what you did below didn’t change how it looks on my iPhone 12. I took a screenshot, but I don’t know how to upload it here.

Are you able to test it on a phone?

Thanks for continuing to try and get this fixed.
