Getting started is easy! You can either:

1. Click on one of the Quick Templates buttons to load pre-built examples

2. Start typing directly in the HTML, CSS, or JavaScript panels

3. Your changes will appear in the Live Preview section automatically

The editor saves your work automatically, so you won’t lose your progress!

If your JavaScript isn’t working, check these common issues:

1. Make sure your HTML elements exist before trying to access them

2. Check the browser console for error messages (F12 → Console)

3. Ensure you’re using proper syntax – semicolons, brackets, quotes

4. Try clicking the “Refresh” button to reload the preview

5. Use console.log() to debug your code

The Live Code Editor automatically saves your work locally in your browser using localStorage. This means:

✅ Your code is saved automatically as you type

✅ Your work persists when you refresh the page

❌ Clearing browser data will delete your saved code

❌ Code isn’t synced across different browsers or devices

For permanent storage, copy your code to external files or cloud storage.

You can include external libraries by adding them to your HTML section:

CSS Libraries:

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.0.0/css/all.min.css">

JavaScript Libraries:

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>

Popular options: Bootstrap, jQuery, Font Awesome, Chart.js, Three.js

To create responsive designs:

1. Add the viewport meta tag: <meta name="viewport" content="width=device-width, initial-scale=1.0">

2. Use CSS media queries: @media (max-width: 768px) { ... }

3. Use flexible units: rem, em, %, vw, vh

4. Use CSS Grid or Flexbox for layouts

5. Test the “Responsive Grid” template for examples!

Due to security limitations, you cannot upload local files directly. However, you can:

1. Use online image URLs: <img src="https://example.com/image.jpg">

2. Use free image services like Unsplash, Pexels, or Picsum

3. Use placeholder services: https://via.placeholder.com/300x200

4. Convert images to base64 data URLs (for small images only)

5. Use CSS for decorative elements instead of images when possible

Common CSS issues and solutions:

1. Typos: Check spelling of properties and selectors

2. Specificity: Use more specific selectors or !important

3. Missing semicolons: End each CSS rule with ;

4. Wrong selectors: Ensure class names match: .my-class in CSS, class="my-class" in HTML

5. Cache: Try refreshing the preview or clearing browser cache

To export your project:

1. Single HTML file: Copy all code and combine into one HTML file with <style> and <script> tags

2. Separate files: Copy HTML to index.html, CSS to styles.css, JS to script.js

3. CodePen/JSFiddle: Copy each section to respective panels

4. GitHub: Create a repository and upload your files

5. Web hosting: Upload to services like Netlify, Vercel, or GitHub Pages

Useful keyboard shortcuts while coding:

Text editing:

• Ctrl+A (Cmd+A): Select all

• Ctrl+C/V (Cmd+C/V): Copy/Paste

• Ctrl+Z (Cmd+Z): Undo

• Tab: Indent (add spaces)

• Shift+Tab: Outdent (remove spaces)

Browser:

• F12: Open Developer Tools

• Ctrl+Shift+R: Hard refresh

The Live Code Editor has practical limits:

• LocalStorage: Usually 5-10MB per domain

• Performance: Very large code files may slow down the editor

• Browser memory: Complex animations or large datasets might cause issues

• Best practice: Keep projects focused and modular

For large projects, consider using a proper IDE like VS Code with a local development server.
