How to make a facebook post embedded on the site rubber?

Question

Facebook

There is a site on Drupal (this is not important). The design of the site is adaptive, adapts to smartphones, tablets, PCs. The site editor needs to insert Facebook posts into the text of articles.
1. The question is how to embed a post so that it obeys the rules of responsive design? Requires the ability to change the width of the post depending on the width of the browser window. The native Facebook mechanism (Embed Post) allows you to set only a static width. I consider any solutions (css, js, plugins, any other tools).
2. A less important question (but it may help to solve the first one). There will be a lot of content on the site. It would be desirable not to depend on API changesfacebook. So that workarounds for question 1 do not lead to a breakdown of all posts on the site with some changes on facebook. It is quite possible that the posts will be static. That is, they were not constantly pulled up from Facebook, but formed when added. So to say the html "screenshot" of the post .
