Iphone enlarges the page very much, what to do?

Question

iPhone

I make a little animation and use the following thing for phones:

meta name="viewport" content="width=device-width"

(<> - removed because the toaster does not display)
On android phones it works like a clock, but under ios it does not work correctly.
They grow out of proportion. Tell me how should I be?

Answer 1

one.

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0">

2.

body { -webkit-text-size-adjust: none;
    text-size-adjust: none; }

3.body { overflow-x: none; }
