Adding the Lottie Animation Block

To add a Lottie Animation Block to your page:

  1. Click the “+” icon to open the block inserter
  2. Search for “Lottie” or navigate to the “DigiBlocks” category
  3. Click on the “Lottie Animation” block to add it to your page
  4. The block will appear with a placeholder where you can upload a file or enter a URL

The block will display a placeholder with options to either upload a Lottie file or provide a URL to a Lottie JSON file.

Source Configuration

File Upload Method

When using the file upload method:

Supported File Types: JSON files, plain text files, and other formats containing Lottie animation data

Upload Process:

  1. Click “Upload Lottie File” in the placeholder or inspector controls
  2. Select your Lottie JSON file from the media library or upload a new one
  3. The animation will automatically load and begin playback based on your settings

File Management:

  • Replace existing animations using the “Replace Lottie File” button
  • View the current filename below the upload button
  • Files are stored in your WordPress media library for reuse

URL Method

For external animations or CDN-hosted files:

URL Requirements: Direct links to JSON files containing Lottie animation data

Loading Process:

  1. Switch to “URL” in the source type selection
  2. Enter the complete URL to your Lottie JSON file
  3. Click “Load Animation” to fetch and display the animation

URL Examples:

  • https://example.com/animations/loading.json
  • https://assets.website.com/lottie/hero-animation.json
  • CDN links from services like LottieFiles

Source Type Switching

You can easily switch between file and URL methods:

  • Use the radio buttons in the inspector controls
  • Click “Or use URL instead” / “Or upload a file instead” in the placeholder
  • Switching preserves your animation settings but clears the source

Animation Controls

Alignment Options

Horizontal Alignment:

Performance Optimization

Loading Strategy

The Lottie Animation Block implements several performance optimizations:

Script Loading:

  • Lottie library loads only when needed
  • Prevents unnecessary resource loading on pages without animations
  • Handles loading states gracefully with user feedback

Animation Management:

  • Proper initialization and cleanup procedures
  • Memory management for animation instances
  • Efficient rendering with minimal performance impact

Error Handling:

  • Graceful fallback for failed animation loads
  • User-friendly error messages with retry options
  • Prevents page crashes from malformed animation files

Best Practices for Performance

File Size Optimization:

  • Keep Lottie JSON files under 500KB when possible
  • Optimize animations in After Effects before export
  • Remove unnecessary layers and effects
  • Consider using simplified versions for mobile devices

Usage Guidelines:

  • Limit the number of simultaneously playing animations
  • Use autoplay sparingly to reduce initial page load impact
  • Consider using intersection observers for below-the-fold animations
  • Test performance on lower-end devices

Troubleshooting Common Issues

Animation Not Loading

File Format Issues:

  • Ensure files are valid Lottie JSON format
  • Check that files aren’t corrupted during upload
  • Verify file extensions are correct (.json)

URL Problems:

  • Confirm URLs are publicly accessible
  • Check for CORS restrictions on external files
  • Ensure URLs point directly to JSON files, not HTML pages

Browser Compatibility:

  • Test in different browsers for consistent behavior
  • Clear browser cache if animations don’t update
  • Check for JavaScript errors in browser console

Performance Issues

Large File Sizes:

  • Compress animation files using Lottie optimization tools
  • Reduce animation complexity in After Effects
  • Consider splitting complex animations into smaller segments

Multiple Animations:

  • Limit concurrent autoplay animations
  • Use intersection observers for animations below the fold
  • Consider lazy loading for non-critical animations

Styling Problems

Size Issues:

  • Check that container dimensions are appropriate
  • Verify responsive settings for all devices
  • Ensure parent containers don’t restrict sizing

Positioning Problems:

  • Review margin and padding settings
  • Check alignment settings and container constraints
  • Verify CSS conflicts with theme styles
