I'm sorry that I haven't been in touch for a while. I've had a lot going on with my family. I've been sick a lot and had important things to take care of.
Anyway, thank you very much for following up several times. Unfortunately, it hasn't been resolved yet.
After I uploaded the second version of the logo to the /images directory and edited the code as described, the logo disappeared completely when I scrolled down.
It's also particularly bad in the mobile view.
Would you please investigate again and help?
Thanks in advance!
