Lots of people are interested in this at different places, but I couldn't find a direct solution. One can use the template from here.
A part of it is answered here and a simple tweak would be to reduce the page width via geometry package as
But what I want is to issue this command only from the second page and so-forth, for the first page it should respect the default margins and whenever text flows to second page, its get wider to page width.
I am using \newpage to manually define which sections should go on to the second page, as side page is a waste on the second page.
Could someone help me on this? Have a good day!
