I probably had the same look on my face, the one grandma always had when she came face to face with a PC, ever confused. I went blank when I heard her asked, “it doesn’t work on my phone, do you have a mobile website?” Say, what?!
I learned then that the cyber world I though I knew had already changed! I am not talking about years, but months, since I last launched my so-called modern website! So it is. Nevertheless, I am not too old to keep up! :p
My best advice, build your website with HTML5. It works on iPad, android, iPhones, and PCs. Have a lovely day, and thanks for reading!
