Edit HTML & See Instant Preview

The HTML Live Preview Tool template provides a split‑screen interface: one side for editing HTML (code input) and the other side showing the rendered result live. This instant feedback loop helps users experiment with markup, test layouts, or demonstrate HTML snippets easily. Built with Trickle AI, it’s ideal for dev demos, tutorials, or web editors.

Key Features

  • Live rendering of HTML code input
  • Split view: code editor + preview pane
  • Responsive design to support editing on various devices
  • Lightweight, instant update as you type
  • Minimal UI so focus stays on code and output

Use Cases

  • Teaching HTML & frontend basics with live examples
  • Prototyping small web components or layouts
  • Embedding an HTML editor + preview in documentation
  • Interactive tutorials or code playgrounds
  • Portfolio demos showing code skills side by side

Make sure your preview doesn’t break with malformed HTML by sanitizing or fallback rendering. Use this tool for small experiments and snippets rather than full pages with external dependencies. Keep UI minimal so focus stays on code-output feedback.

  • Limit complexity in HTML preview (avoid external CSS/JS)
  • Provide simple placeholder CSS for basic styling
  • Sanitize or escape harmful tags for safety
  • Update preview on debounce (not every keystroke) for performance
  • Test responsive behavior to ensure preview pane adapts

Who Is It For?

  • Web development educators and instructors
  • Frontend developers prototyping layouts
  • Tutorial authors needing live HTML examples
  • Documentation sites embedding interactive HTML demos
  • Coders showcasing both markup and visual result
