Tailwind CSS comes with "an opinionated set of base styles" called Preflight. A helpful CSS reset built on top of modern-normalize.

Margins, headings, lists, and many others get stripped from their defaults. Thus, achieving cross-browser consistency and an easier adaptation of your design system.

It all sounds helpful, until you need those defaults to style a markdown post.

In comes @tailwindcss/typography, a plugin with sensible typographic styles. It adds a set of prose classes to style content blocks like the one you are reading.

You can install it via npm or yarn:

# Using npm
npm install @tailwindcss/typography

# Using Yarn
yarn add @tailwindcss/typography

Then add the plugin to your tailwind.config.js file:

// tailwind.config.js
module.exports = {
  theme: {
    // ...
  },
  plugins: [
    require('@tailwindcss/typography'),
    // ...
  ],
}

Finally, you can use the prose class to apply the markdown styling:

<article class="prose lg:prose-xl">
  <h1>Welcome to Mars!</h1>
  <p>
    Although life on Mars is perfect in every single way, you might have some questions.
  </p>
  <p>
    Of course there’s air! Just don’t breathe it. And, with the crazy gravity situation, everyone can dunk!
  </p>
  <!-- ... -->
</article>

More information about the prose class and its modifiers can be found in the repository.
