At least on iOS, this only works from the left edge of the screen. You can't "swipe the entire page right", only the left edge. But perhaps I'm misunderstanding what you meant there.
Safari on iOS uses swiping from the left edge to let you swipe back to the previous page, so websites couldn't reliably implement that feature this way.
I wonder if any of the popular Android browsers also use the left edge to let you swipe to previous pages?
Websites could certainly let you swipe left to right over any part of the page to pull out the menu, which is what I thought you were talking about, but that's not what mobile apps commonly do.
I use Android.
- The Facebook app lets you swipe left-right between sections of the app
- Gmail, Slack, Drive all let you pull menus out of the left.
These are just some obvious examples but MANY apps support navigation in this way.
