I'm an amateur web dev, is that really all it takes with HTML?
More or less if you use JS to fetch the link and parse the meta tags in its header. Lemmy does that when you submit a post with a link, and it'll pull the title, description, image, and video properties and include them with the post detail.
From there, it's just a matter of detecting those and rendering them.
ogis shorthand for open graph, it’s a standard Facebook started for capturing page metadata to use in embedded previews and has caught on to wide adoption. It’s not an official HTML tag but it’s very ubiquitous today.
