Thanks so much.   Yes, I am aware of this code and have also sighted it and this is not the issue though unfortunately.  It's not this coding because I tested it and removed it using inspect a few days ago and it didn't make a difference. I don't know how it's happening because there's no padding or margin or line-height to make the text hidden.
The mobile site looks fine on several phones that I've tested... however, the iPad not so good. 😞
So I still haven't found what's causing the obscured text. 
I know about the logo too thanks.  It's a staging environment so still a few things to sort out.
I agree, lots of nested coding and it does my head in.
