The attached document shows how to embed a Twitter, Facebook, and Google+ share button.
SocialButtons.hype.zip (323.7 KB)
One thing to keep in mind:
Some social buttons do not include the protocol. They have URLs that reference required JavaScript functions like //cdn.site.com
This is great for most purposes, but not all. You may want to edit the source to include https://cdn.site.com
– this ensures that if you are loading your document somewhere (like an iBook Widget), the protocol is correctly picked up by the viewer.
