This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including markdown-it-attrs. Try it out:
const md = require('markdown-it')();
const markdownItAttrs = require('markdown-it-attrs');
md.use(markdownItAttrs);
let src = '# header {.style-me}\n';
src += 'paragraph {data-toggle=modal}';
md.render(src);
