physicalgrafitti75 on "Phone number display from website not displaying on Iphones"

The website I maintain for a business owned by a friend is having issues showing the phone number from the home page on mobile phones, specifically Iphones. I have read the forums on this topic and it seems that I need to download a mobile website builder - Duda seems to be the most recommended.

The frustrating part is that the only field that does not show up on Iphones is the phone number which is displayed in the upper right of the home page. That is generated via our custom built theme - everything else display's including "Open 7 Days a Week" and the business address, which is all in the same DIV on the custom theme.

Question is:

Do I really have to have a separate website builder for smart phones only?

I don't see why I cannot get a number to display on a page.

Website is geragardens.com

I am a computer programmer - I work on mainframes and have been for almost 30 years now, but was never trained in website design and coding, so while I can update his site with new pictures and prices, I am a novice when it comes to WordPress / HTML / CSS.

Any help would be greatly appreciated.

THANKS
