Tailwind Playground
Write HTML with Tailwind CSS v4 utilities and compile it live in your browser.
What is the Tailwind Playground?
It is a free in-browser editor where you write HTML with Tailwind CSS v4 utility classes and see the compiled result in a live preview. The official Tailwind v4 browser compiler is bundled into the page, so nothing needs to be installed.
Is my code uploaded anywhere?
No. Compilation happens entirely inside your browser with a locally bundled copy of the Tailwind engine. Your HTML never leaves the page, and drafts are stored only in your browser's localStorage.
Which Tailwind version does it use?
It uses Tailwind CSS v4, the latest major version, running through the official @tailwindcss/browser compiler. All core utilities, variants and the default theme work, including arbitrary values in square brackets.
How does the live preview work?
Your HTML is injected into a sandboxed iframe together with the compiler. Every edit recompiles the utilities after a 500-millisecond pause, so typing stays smooth while the preview stays current.
How do I test dark mode styles?
Tick the "Dark preview" switch. It adds the class "dark" to the preview document and the compiler maps the dark: variant to that class, so utilities like dark:bg-slate-900 respond immediately.
Can I see the CSS that Tailwind generates?
Yes. The "Compiled CSS" panel under the editors shows the exact stylesheet the compiler produced for your markup, and the "Copy CSS" button copies it to your clipboard.
What does the downloaded HTML contain?
The Download HTML button produces a standalone file with your markup plus the compiled CSS inlined in the head, so the page renders correctly offline without any CDN link or internet connection.
Are there starter templates?
Yes. The template selector offers a hero section, a responsive card grid and a three-tier pricing table, all written with current v4 utilities, plus a minimal blank starting point.
How to Use Tailwind Playground
This playground runs the official Tailwind CSS v4 browser compiler entirely on your machine. You type plain HTML with utility classes on the left, the compiler generates the matching CSS inside a sandboxed preview iframe, and a panel below shows the exact stylesheet that was produced. Nothing is uploaded: the compiler, your markup and your drafts all stay in the browser.
- Pick a starting point from the Template selector: Hero, Card grid, Pricing table or Blank; your text is also restored automatically between visits.
- Edit the HTML in the left editor. Pressing Tab inserts two spaces, and the preview recompiles about 500 ms after you stop typing.
- Toggle Soft wrap to control line breaking, and the font size selector to set the editor text size.
- Switch on Dark preview to add the class "dark" to the preview document; utilities such as dark:bg-slate-900 respond instantly.
- Read the generated rules in the Compiled CSS panel and copy them with Copy CSS when you need them.
- Use Copy HTML for the raw markup, or Download HTML to get a standalone file with the compiled CSS inlined, ready to open offline.
The download only has real styles after at least one compile, so let the preview render once before exporting. To reduce the generated CSS, delete unused elements from the template — the panel always reflects exactly what your current markup needs.
