I have a small map on my page, and want to allow the user to look at a larger version of it if a link is clicked.
On this new page, the map will essentially be full screen, covering everything except for a little "back button" in the top left.
Is this OK? Or would it be preferable to maintain my main menu, and make the map as large as I can, keeping the main menu visible.
I guess this boils down to the fact that if the user clicks on the "view large map", the only way they can carry on browsing the site is by clicking the back button.
