Displays an instagram embed.
Example:
The width and height attributes are special for the instagram embed.
These should be the actual width and height of the instagram image.
The system automatically adds space for the "chrome" that instagram adds around the image.
Many instagrams are square. When you set layout="responsive" any value where width and height are the same will work. If the instagram is not square you will need to enter the actual dimensions of the image.
When using non-responsive layout you will need to account for the extra space added for the "instagram chrome" around the image. This is currently 48px above and below the image and 8px on the sides.
shortcode
The instagram shortcode found in every instagram photo URL.
E.g. in https://instagram.com/p/fBwFP fBwFP is the shortcode.
