About this tool
Preview HTML in the page when you are sketching an email snippet, a landing block, or a student exercise — without deploying a server.
Live preview is for learning and for catching missing tags before you paste into a CMS. It is not a full production sandbox: scripts may be limited, and third-party pixels should not be tested with real customer data here.
Write semantic HTML. Check how Arabic RTL looks if the fragment will go on 1CLIK or a bilingual site. Pair with HTML Beautify when the paste arrived as one minified line.
Never preview HTML you do not trust (random attachments). Malicious markup is rare in your own drafts and common in “free template” downloads. Keep the playground for code you wrote or reviewed.
Quick steps
- Paste or type HTML in the editor.
- Watch the preview pane update.
- Fix tags, then copy the markup out.
- Test again in the real CMS or email tool.
Markup stays in the tab. We do not publish your snippet to the public internet.
FAQ
Can I use CSS/JS?
The dedicated HTML/CSS/JS Playground is better for multi-file experiments.
Email HTML?
Email clients are quirky. Preview here, then test in Litmus or actual Gmail/Outlook.
PHP or Blade?
This is client-side HTML only. Server templates will not execute.
