Typography Showcase

The Power of Markdown

This section exists to stress test your typography styles. We need to ensure that italics, bold text, and even strikethrough text look perfect.

Nested Lists

Lists are crucial for clarity. Here is how we handle complexity:

  1. Frontend Layer
    • React 19
    • Tailwind CSS
    • Framer Motion
  2. Backend Layer
    • PostgreSQL
    • Prisma ORM
      • Schema validation
      • Migrations

Blockquotes

Sometimes we need to quote wisdom:

"Premature optimization is the root of all evil." — Donald Knuth


Code & Technical Details

Syntax Highlighting

We need to support multiple languages.

TypeScript:

interface User {
  id: number;
  name: string;
  role: 'ADMIN' | 'USER';
}

const getUser = (id: number): User => {
  return { id, name: "Max", role: "ADMIN" };
}

CSS / Tailwind:

.btn-primary {
  @apply px-4 py-2 bg-blue-500 text-white rounded;
}
