How do you make a facebook style comments board where it auto refreshes and slides down as new content appears at the top? Or where can I find such code? Look at the bottom of this article for an example of what I mean:
I see these everywhere now. I created something similar a few years ago, but new posts just pop up every 20 seconds. I'm wondering how to get that loading icon and then have the previous comments slide down smoothly.
Thanks in advance.
