title: How do I create a show full screen button to toggle my google maps page to be full screen?
body: <p>I have a google map integrated on part of my page. I would like to create a toggle button to toggle the map between full screen and normal size. So when you click on it - the map extends to fill the whole browser screen, and click on it again, it is restored to its original size on the page. How would I do it?</p>
