What is the Tailwind Typography Plugin?
The @tailwindcss/typography plugin adds the prose class, which applies a complete set of sensible typography defaults to any raw HTML block. Instead of manually styling every heading, paragraph, list, and quote in a blog post or article, you wrap the content in class="prose" and get beautiful, readable typography out of the box.
This preview tool lets you see exactly how your content will look across every prose size — from prose-sm to prose-2xl — and with every color modifier (slate, gray, zinc, neutral, stone). It is invaluable for picking the right size for your site and for verifying that the plugin's output matches your design system before you deploy.
How to Use
- Select a prose size (sm, default, lg, xl, 2xl) to see how the typography scales.
- Choose a color modifier to match your site's design system (slate, gray, zinc, neutral, stone).
- Preview the rendered content live. The
proseclass is applied automatically to the wrapper. - Copy the HTML code to use in your project. Requires
@tailwindcss/typographyplugin installed.
Frequently Asked Questions
How do I install the typography plugin?
Run npm install -D @tailwindcss/typography and add require('@tailwindcss/typography') to your tailwind.config.js plugins array.
Can I combine prose with other Tailwind classes?
Yes. Add additional classes to the container alongside prose. For example, class="prose prose-lg dark:prose-invert" handles dark mode too.
Why does my prose content ignore global heading styles?
The plugin scopes its styles inside the prose wrapper so raw HTML looks like a well-formatted article regardless of your global styles. To customize, override the theme keys such as typography.sm or typography.DEFAULT in tailwind.config.js.
Does this tool store the content I preview?
No. Everything happens in your browser. The sample article is generated locally and never sent to any server.
