Does the same content on the same page in two divs affect SEO?

Question

css

Good day!
There is a site with a mobile version, in terms of layout - two different divs - for desktop and mobile devices, respectively, visibility is controlled through display.
Will search engines consider these divas as duplicate content and will there be consequences from such layout?

Answer 1

Yes, it does. There will be duplicate content, this is bad.

Answer 2

I think it will be considered a duplicate. Google bot opens the site without styles, just HTML

Answer 3

The only possibility is to place the mobile version of the site in a separate directory: https://YourSite/mobile
