🎨 Tailwind CSS Playground
Edit HTML with Tailwind CSS classes and see live preview
About this tool
A live HTML editor with Tailwind CSS loaded automatically — type markup with utility classes on the left and see the rendered result instantly on the right. It is the fastest way to prototype a card, hero section, pricing table, or any small UI component without setting up a project or running a build step.
Type or paste HTML that uses Tailwind classes, and the preview updates as you type (debounced 500 ms). Switch between Tailwind v3 and v4 from the version dropdown. Use the desktop / mobile toggle to check responsive layouts at 375 px width. Three starter presets (Card, Hero, Pricing) give you a starting point you can tweak.
Example: paste <div class="p-6 bg-blue-500 text-white rounded-xl">Hello!</div> into the editor and you see a blue rounded box with white text immediately.
FAQ
Do I need to install anything? ›
No. Tailwind CSS is loaded from a CDN inside the preview iframe, so all utility classes are available the moment you start typing. You do not need npm, a build step, or a local server.
Is the preview safe to run JavaScript in? ›
Yes. The preview iframe is sandboxed with allow-scripts and allow-same-origin, so <script> tags inside your HTML run but are isolated from this page and your browser. You can test interactive components safely.
Can I use my own CSS alongside Tailwind? ›
Yes. Add a <style> tag inside the editor, or include arbitrary CSS classes alongside Tailwind utilities. For custom Tailwind theme values, you can add an inline config script in your HTML using the tailwind.config pattern supported by the play CDN.
Does the preview reflect mobile layouts? ›
Yes. Click the mobile (📱) button to constrain the preview to 375 px width, which is a common phone breakpoint. Click the desktop (🖥️) button to return to full width.
What is the difference between this and the HTML Playground? ›
This Tailwind Playground focuses solely on HTML with Tailwind CSS for rapid UI prototyping — it loads Tailwind from CDN and keeps the editor minimal. The <a href="/tools/html-playground/">HTML Playground</a> is a general-purpose sandbox with separate HTML/CSS/JS editors, a console panel, and three layout modes, making it better suited for full-stack frontend experiments, debugging CSS bugs, or testing JavaScript logic.
