This tool is a Real-Time HTML Sandbox, designed for instant code experimentation and prototyping. It provides a streamlined, distraction-free environment where you can write code and see the
visual results immediately as you type.
Live Coding: Write HTML structure and CSS styles in the editor panel and watch the preview update instantly without needing to refresh the browser.
Visual Debugging: Test layout ideas, UI components, or typography settings in a sandboxed iframe that keeps your experimental code isolated from the rest of the application.
Responsive Testing: The preview is housed in a "viewport shell," allowing you to see how your code renders within a controlled container.
Dark-Mode Workspace: The interface uses a high-contrast dark theme to reduce eye strain during long coding sessions.
