HTML Viewer Tool

About the HTML Viewer Tool

The HTML Viewer Tool provides a fast, safe, and responsive environment to paste, edit, and preview HTML code in real-time. Designed for developers, designers, students, and content creators, this tool renders your HTML instantly in a sandboxed preview so you can prototype UI, test snippets, debug markup, or learn HTML without setting up a local server.

Key Features

  • Live Preview: Updates instantly as you type — no extra clicks required.
  • Responsive Layout: Two-panel editor + preview that stacks on mobile.
  • Sandboxed Preview: Renders output inside a safe iframe to avoid interfering with the page.
  • Monospace Editor: Clean, readable code area with vertical resizing.
  • WordPress-ready: Works inside Custom HTML blocks or Elementor HTML widgets.
  • Lightweight & Client-side: Runs fully in the browser — no server or account needed.

Common Uses

  • Quickly prototype HTML snippets for webpages or components.
  • Preview email-friendly HTML or landing page fragments.
  • Teach or learn HTML with live visual feedback.
  • Test embedded widgets, small JS examples, or CSS experiments.
  • Validate markup and inspect rendering across device sizes.

How to Use the HTML Viewer Tool

  1. Paste or type your HTML code into the left-hand editor area.
  2. As you type, the right-hand preview will update automatically to show the rendered output.
  3. Resize the editor or preview panel vertically if you need more space for long code or results.
  4. To test external CSS or JS, include them with <link> or <script> tags in your snippet — remember the preview runs inside a sandboxed iframe.
  5. If you want to save or reuse snippets, copy the code from the editor and keep it in your editor or notes app.

Note: The preview runs in the browser and is sandboxed for safety. Avoid pasting sensitive data. This tool is intended for development, learning, and testing small snippets.
