Deep dive

Technical Implementation

This loading animation is implemented with pure CSS technology, creating continuous loop animation effects through carefully designed @keyframes rules. Core technologies include:

Key Technical Points

  • Animation Loop: Uses animation-iteration-count: infinite for infinite loops
  • Timing Control: Creates staggered effects through animation-delay
  • Transform Combination: Combines properties like scale, rotate, opacity
  • Performance Optimization: Avoids property changes that trigger reflow/repaint

Reuse steps

  1. 1Create basic HTML structure: Set up container and elements for loading animation
  2. 2Define keyframe animations: Use @keyframes to describe animation states
  3. 3Set animation properties: Configure duration, delay, iteration-count, etc.
  4. 4Optimize animation performance: Use transform properties instead of position changes
  5. 5Add responsive adaptation: Ensure proper display on different devices

Performance notes

Use transform and opacity properties for animations to achieve optimal performance; avoid using layout properties like width, height in animations; consider using prefers-reduced-motion media query to respect user preferences
