I can't get my code to scale properly on different devices. I'm having a "meta" crisis.

Question

Is there something wrong with the "meta=viewport" tag or is there a secret way I'm supposed to lay things out in the tag? I started out on my laptop but when I went to the app on my mobile I was surprised the whole ensemble was off. I've looked online and on YouTube, I just can't find one that works.

Answer 1

I think sometimes it is you phone compatibility. For instance, most of the time my phone can't play animations. I'm using ASUS.

Answer 2

I have a BLU cellphone and I think is working for me.

Answer 3

I have a ZTE. I hope my phone isn't the problem.

Answer 4

Maybe you can try to:
1 - Do scale in other way.
2 - Reboot your phone.
3 - Uninstall SL app and try installation again.

Answer 5

I've tried different formats. None gave the desired output.
