About This Web Code Viewer Tool
Our Web Code Viewer is an essential online tool for developers, designers, and educators who work with HTML, CSS, and JavaScript. This powerful utility allows you to write or paste your code and instantly see the results in a live preview panel. Whether you're testing a small code snippet, debugging a layout issue, or teaching web development concepts, this tool provides a seamless, real-time coding experience right in your browser.
The tool supports both separate code input (HTML, CSS, and JavaScript in dedicated panels) and combined HTML input for those times when you're working with a single file. The intuitive interface and immediate feedback make it perfect for rapid prototyping and experimentation without the need for complex development environments.

How to Use This Tool Effectively
Using our Web Code Viewer is straightforward. Simply paste your HTML, CSS, and JavaScript code into their respective tabs in the editor panel. For combined HTML files (with embedded CSS and JavaScript), switch to the "Combined Code" tab and paste your complete HTML document. Click "Run Code" to see your creation come to life in the preview panel.
For optimal results, remember to include a complete HTML structure when using the combined view. The separate code panels automatically wrap your CSS and JavaScript in appropriate style and script tags. Use the reset button to clear all fields and start fresh with a clean slate.

By testing code snippets here first, you prevent potential issues from affecting your live WordPress site.
The responsive design ensures the tool works flawlessly whether you're working from your desktop in the WordPress admin area or testing on mobile devices. The clean, intuitive interface integrates seamlessly with WordPress without disrupting your site's existing header and footer.
