Extra large on cell phone

[pgscannell]

I cannot post on stack overflow. Hopefully you will get this question.

The demo link works fine on all devices. Since I need a signature pad on one of my web pages, I copied all if your code to my PC and incorporated it into my page as an iframe. It works perfectly on my desktop.

However, when I run it from my cell phone, the canvas and the signstures are at least twice as large as it should be. I can't figure it out, especially since the demo (which is the same code) works perfectly.

Also, where does rhe demo page get its styles from? There isn't a css load in the code.

Please respond to my email: paulgscannell@gmail.com

Thanks,
Paul
