About This Online HTML Editor & User Guide

Welcome to our Online HTML Editor! This tool is designed to provide web developers, designers, and HTML learners with a convenient and efficient environment for coding, testing, and previewing. You can write, modify, and run HTML, CSS, and JavaScript code directly in your browser without any software installation.

Key Features:

• Real-time Code Editing: A feature-rich code editor (powered by CodeMirror) supporting syntax highlighting for HTML, CSS, JavaScript, auto-completion (partial), bracket matching, and more.
• Code Formatting: Beautify your HTML code with a single click, making it well-structured and easy to read. Say goodbye to messy code and improve maintainability.
• Code Minification: Effectively reduce the size of your HTML files to optimize web page loading speed, especially useful before deploying to a production environment.
• Instant Live Preview: Click the "Preview running" button to see the actual rendered output of your current HTML code in a new window or tab, facilitating debugging and validation.
• Content Operations: Easily undo, redo, clear editor content, copy all code with one click, and download your code as an .html file.
• Line Wrapping: Toggle automatic line wrapping on or off to suit your coding preferences and manage long lines of code.

How to Use This Editor Effectively:

1. Write or Paste Code: Directly type your HTML, CSS, or JavaScript into the editor area. You can also copy and paste existing code from other sources.
2. Utilize the Toolbar:
   
   • Use the Undo and Redo buttons to revert or reapply your editing actions.
   • Check/uncheck the Enable line wrapping checkbox to control how long lines of code are displayed.
3. Format and Optimize:
   
   • When your code looks messy, click the "Format" button, and the editor will automatically organize indents and layout.
   • To reduce file size, click the "Compress" button, which will remove unnecessary spaces and line breaks.
4. Preview and Debug: Click the "Preview running" button to open a live view of your current code in a new tab. This is a crucial step for verifying your code's correctness. If the new page doesn't display content after a refresh, ensure your browser allows pop-ups and check if the optimized preview logic from a previous update has been deployed.
5. Get and Share Your Code:
   
   • Once editing is complete, click the "Copy result" button to copy all the code to your clipboard.
   • Click the "Download file" button to save the content from the editor as an HTML file to your local computer.
6. Clear Content: If you want to start over, click the "Clear" button.
