Responsive page plugin

I was wondering how to make the new page plugin responsive like the old one used to be, then I finally found this: https://developers.facebook.com/docs/plugins/page-plugin#adaptive-width

In short, you simply need to set the width (in the block settings) to something that'll always be larger than the region where the plugin is displayed. For example, if your Facebook block is displayed in a sidebar with a maximum width of 300px, set the width of the plugin to >300px and it'll resize accordingly.

It might be worth documenting this somewhere.
