How to make mirror margins when printing from a browser?

Question

css

Interested in how to make mirror margins when printing, as in Word.
The standard chrome tools don't fit, or I didn't search well.

Answer 1

You need to define print styles via CSS

@media print {
   …
}

Answer 2

Nothing is clear in your question. Give an example of what needs to be done

Answer 3

This is not in the standard functionality of the print version.
You can develop a completely separate version of the site, and set the indents (margins) there, as Falseclock advises .
To do this, you will need to EXACTLY fit the site to the A4 page so that all browsers correctly determine.
Perhaps there is such a setting inside browsers, but not all.
Either way, CSS or JS won't solve your problem.
