I have a page in my website, for example site.com/how-to-become-uber-driver for blackhat reasons, I want to temporarily change the content on this page. I could copy/paste the content of the current page, save it on my computer, delete the page, recreate the page, put up the new content, delete the new content, paste the old content. but I am afraid in the process I will mess up the formatting, I remember I was having a lot of formatting problems and had to hire someone to fix it. so I would rather have the old page sitting in the backend, in a way that I can easily turn it on and off. how can this be accomplished?
