What is a Facebook post?

Question

Facebook

Friends, I can not understand how such posts are published. I saw them only on the pages of foreign publications. It works like this: you tap on the publication, it instantly opens and at the same time, as you can see on the screenshots, the type of publication with the corporate style of the site. In addition, the article opens instantly.
How can I make posts open from my site in this way? Thank you!
