To display a Google Calendar, Google Map or other iframe content, use a short code, enclosed in square brackets.

[iframe src="" width="100%" height="500"]

Please keep width=”100%”, as this will fill the available space on most devices and screen widths. The height value is set in pixels only; you can change this to suit your needs.

Copy only the URL/link from the iframe code you got from Google.
Paste the URL into the src attribute of the short code.
