Balanced Responsiveness and Intentional Activation
This demo uses scrollThreshold: 10 - a medium threshold
that requires moderate scroll speed to activate the natural scroll-in
effect. This creates a balance between responsiveness and intentional
interaction.
💡 Try this: Scroll down, then try scrolling up with different speeds. Notice how gentle scrolling doesn't trigger the effect, but moderate scrolling does.
Perfect for: General-purpose websites where you want a balance between accessibility and preventing accidental activation.
⚖️ How Medium Threshold Works
// Medium threshold configuration
naturalStickyTop(header, {
scrollThreshold: 10,
snapEagerness: 1
});
// This means:
// - Header activates when upward scroll speed ≥ 10px per scroll event
// - Requires moderate scrolling intention
// - Prevents accidental activation from tiny scroll movements
// - Still accessible but more deliberateThe medium threshold strikes a balance between ease of use and intentional interaction. It filters out small, accidental scroll movements while still being accessible for deliberate navigation.

🎯 Behavioral Characteristics
Here's what happens with scrollThreshold: 10:
- ✅ Requires moderate scroll speed to activate
- ✅ Prevents activation from tiny accidental movements
- ✅ Good balance of accessibility and intentionality
- ✅ Works well with both mouse and trackpad
- ✅ Suitable for most general-purpose websites
📈 Scroll Speed Requirements
Medium threshold requires a more deliberate scroll motion. When you scroll up with speed ≥10 pixels per scroll event, the header positions itself above the viewport to naturally scroll back into view.
🎭 UX Insight: Medium thresholds create a more refined interaction - users need to show clear intent to reveal the header, reducing visual noise from accidental triggers.
🔍 Practical Applications
Medium threshold is ideal for:
- E-commerce sites: Header appears when users actively look for navigation
- News websites: Doesn't interrupt reading flow with accidental activations
- Corporate websites: Professional feel with intentional interactions
- Portfolio sites: Subtle header behavior that doesn't distract from content
- Landing pages: Clean experience with deliberate navigation access
🧪 Testing Different Scroll Patterns
Try these scrolling techniques to feel the threshold in action:
- Tiny movements: Small mouse wheel clicks - header won't appear
- Moderate scrolling: Normal scroll speed - header appears naturally
- Fast scrolling: Quick movements - immediate activation
- Trackpad gestures: Two-finger scroll with moderate pressure
🎯 Design principle: The threshold acts as a natural filter, ensuring the header appears when users actually want to navigate, not just during casual browsing.
📊 Comparison with Other Thresholds
How medium threshold compares:
- Lower than high threshold: More accessible than high values (20+)
- Higher than low threshold: Less sensitive than low values (2-5)
- Sweet spot: Good for most use cases and user types
- Versatile: Works well across different devices and input methods
The medium threshold demonstrates how scrollThreshold gives you fine control over the user experience. You can tune the sensitivity to match your site's personality and user expectations.
Remember: regardless of the threshold, the movement itself always feels natural because the header moves with the scroll, not against it. The threshold only controls when the positioning happens.
