This demo shows how to embed a Google Calendar so that it is responsive. The basic technique is to wrap the iframe embed code you get from Google with a div. We give that div the class name googleCalendar. Then we set the Google Map iFrame inside of that to cover the width and height of the googleCalendar div. You can change the width and height of the googleCalendar div and the calendar till change along with it.
