Hi Steve,
Thanks so much for reaching out!
Just to let you know, we are limited by our Support Policy in how much we can help with customizations, but I will try to point you in the right direction.
Do you have breakpoints set up for your website? In other words, these are specific styles that go into effect with different screen sizes. If that is the case, I’d recommend adding the code that you have to your mobile breakpoints as well.
You can also add breakpoints in for your mobile styles if you don’t have these set up already.
Let me know how this goes!
Thanks,
Jaime
