Step 1 Technical Breakdown & Concepts
Understanding Harmonic Sine Waves, Staggered Delays, and 3D Perspective Scaling.
Key Technical Details
- ›Each .pair row contains left node, connecting bar, and right node.
- ›Flexbox alignment centers the pair horizontally.
- ›Glow filters prepare nodes for 3D illumination.
Important Takeaway
Clean node pairing simplifies 3D wave mathematics.
