Sticky Cart Bar.
Frictionless throughflow. Maintain persistent access to the conversion trigger as visitors navigate deep product narratives.
Mechanism of Action
The Sticky Module monitors the vertical scroll parity of the viewport. Once the primary 'Add to Cart' button exits the visible frame, the secondary sticky bar is injected into the fixed Z-layer, ensuring the purchase vector remains a single tap away.
Configuration Matrix
Spatial Anchors
Deploy to the top (Desktop dominance) or bottom (Thumb-friendly mobile reach) of the viewport.
Trigger Threshold
Define the precise scroll offset (e.g., 300px) required to activate the sticky transition logic.
Variant Synchronization
| Feature | Execution |
|---|---|
| Live Selection | Allows selection of SKU variants directly from the fixed bar. |
| Price Parity | Dynamically updates valuation as variants or quantities shift. |
Mobile Protocol
For handheld optimization, we strictly recommend the Bottom anchor. This aligns with modern 'reach design' standards, placing the buy trigger directly under the user's natural thumb resting position.
