Hi Shameem,
Your explanation is helpful and the solution is much appreciated.
I actually knew that it can be done in functions.php with a child theme, but I was trying to avoid having to make a child theme. If there is no way to get the IOS mobile browsers to abide by the CSS rules, which I did not know, I’ll do it the way you say – and making a child theme doesn’t sound too difficult when I read about it.
Many thanks!
Les
