How to fix scaling in Opera?

Question

css

Good afternoon. A slightly strange question is why a person who visits a certain site (I did) with Opera immediately displays a zoom of 500%. Not on other sites. How is it and what to do?
PS The site, of course, is

<meta name="viewport" content="width=device-width, initial-scale=1">

Answer 1

So maybe he has the scale turned on? Let him press CTRL+0
