A Responsive Facebook Feed
This page shows how to embed a business' Facebook timeline. The only styling needed is to center the facebook iframe within its div, especially if it's located within a flexbox container. The styling rule is in the main.css file.
For complete instructions on how to set this up, go to the Facebook page at: https://developers.facebook.com/docs/plugins/page-plugin/ .
It appears that you can also embed an iframe version, as well.
