In general HTML should work fine
With HTML you can embed in your Micro.blog videos, contact forms etc…
I suggest you to try and see if it works, if not post here the code and the eventual error, so that somebody can look into it in order to help you.
The HTML seems to work when I add it so, fingers crossed, we’re on the right track here. I’ll definitely post again if I run into issues (bound to happen )
I liked your Contact form, and followed it to Letterbird. What an elegant, simple solution for implementing a (free!) Contact form. I’m using Letterbird now as well.
