The ::: containers

Semantic callouts and real layout, from fenced blocks. Nest by adding colons to the outer block.

All container types

Callouts: info, success, warning, danger. Layout: left / right / center, cols, tabs, spoil (spoiler). Any other ::: ClassName becomes a <div class="ClassName">, so you can style your own.

::: info        ::::  cols 1 2        :::: tabs
…content…       ::: col              ::: tab One

Copy as Markdown

With the browser runtime loaded, selecting rendered content and copying puts Markdown source on your clipboard, not HTML.

It round-trips

Tables, lists, math, code, and even generated constructs survive the trip. Copy a rendered QR and you get {{qr …}} back; copy a diagram and you get its {{mermaid …}} source.

Why it matters

Your rendered document stays the source of truth. Paste into any editor, chat, or issue and it is clean, portable Markdown again, ready to re-render anywhere.
