Markdown is a simple way to create html. I’ve found it useful it Teams. You can type it into a post editor and it is rendered as you go. Unfortunately from my pov posts in teams breaks if you paste in Markdown. But in the praise box you can paste in markdown and it renders on the published post.
For example **bold** *italics* [twitter](https://twitter.com)
bold italics twitter
I’ve got a wee script on my mac that will grab links to all my open tabs and make markdown from it so I can open all the pupils posts, copy all the links and paste into a praise thing.
