@pixeltracker I wanted to thank you for this post--I have been using it for a year and a half at this point! I was recently trying to make a splash index.md page for a personal website and discovered that the kramdown and html button cheats can be modified for markdown as well:
url: "https://scratch.mit.edu"
btn_label: "Visit"
btn_class: "btn--info"
