You gave me the code and I pasted it in the child theme functions.php file as you can see in the image attached.

can I insert it in the main theme functions.php, If yes then where should I add, and if I am supposed to add a code in function.php then do I have to simply add it in the end or in a specific space ???
like I asked in image-2 in given link

Is it possible to reduce site DOM elements?
If so, how can I?

I have no child theme, how can I make 1?

Is it possible to paste it directly in functions.php in theme editor?

I am still unable to understand , can you make it easier for me to place the code?

Is using the inner row good for speed or bad?
I used inner rows a lot on the homepage and without preloading elements

AMP settings

Is it possible to hide a section of homepage like a row or column on other devices except for the desktop ?

Why are images not visible in the mobile version?

Why is it that when I have enabled plugin -mobile theme, it rewrites the settings of the amp and then doesn’t work properly.

After deactivating the plugin , I was able to access the site in responsive more of tagDiv template and able to tick all the boxes in the amp.
Currently, because the mobile theme wasn’t working properly at all I deactivated it and using only the amp plugin

and what about these settings?

Isn’t there any way to disable author and editor access to the cloud templates and keep only Admin access?
This can cause issues if an author edits the template from the cloud template section because all main templates are on it.
