UI/Content loader for cards (like fb)

Question

I'm working on finding a solution for a UI/CONTENT loader for my app to load cards with content.

We're using Angular and while the cards load, they are blank and boring. Trying to build some content expectation for the people who will be using it, in the way that facebook does it. They do a nice job.

Here is a link to a screenshot:

I know there are some pretty simple solutions, and I've spent the last few hours searching for "preloaders" of all sorts, but I keep getting ways to load the entire page. I am looking to accomplish only the individual cards themselves, as the app never really "refreshes" the whole page.

Hope I've done a good job of explaining (I am the designer).

UPDATE: this happens very briefly in facebook
