Fast Scrolling Required for Activation
This demo uses scrollThreshold: 25
- a high threshold
that requires fast, deliberate scroll speed to activate the natural
scroll-in effect. Only intentional, rapid upward scrolling will
trigger the header to appear from above the viewport.
💡 Try this: Scroll down, then try scrolling up with different speeds. Only fast, deliberate upward scrolling will make the header appear from above.
Perfect for: Minimal interfaces, immersive content experiences, or applications where header appearance should only happen with clear user intent.
🚀 How High Threshold Works
// High threshold configuration
naturalStickyTop(header, {
scrollThreshold: 25,
snapEagerness: 1
});
// This means:
// - Header activates only when upward scroll speed ≥ 25px per scroll event
// - Requires fast, deliberate scrolling
// - Excellent for minimalist, distraction-free interfaces
// - Only appears when user clearly intends to navigate
High thresholds create a clean, unobtrusive experience where the header stays out of the way during normal content consumption. Users must show clear navigational intent to reveal the header.
Keep scrolling to understand when this approach works best...
⚡ Behavioral Characteristics
Here's what happens with scrollThreshold: 25
:
- ✅ Requires fast, deliberate scroll speed to activate
- ✅ Creates minimal, distraction-free reading experience
- ✅ Excellent for immersive content consumption
- ✅ Only activates with clear navigational intent
- ✅ Perfect for users who prefer minimal UI interference
🎯 When High Thresholds Excel
High threshold values filter out casual scroll movements entirely. The header only positions itself above the viewport when you scroll up with speed ≥25 pixels per scroll event - this requires intentional, fast scrolling motions.
🧘 Zen principle: High thresholds embody "less is more" design philosophy - the header appears only when truly needed, maintaining content focus.
🎨 Ideal Use Cases
High threshold is perfect for:
- Reading platforms: Medium, blogs, documentation - minimal header interference
- Portfolio websites: Let your work shine without UI distractions
- Art galleries: Focus stays on visual content, not navigation
- Immersive experiences: Games, interactive stories, VR-like interfaces
- Mobile-first designs: Mimics mobile app behavior with intentional interactions
🔬 Scroll Speed Analysis
High thresholds require specific user behaviors:
- Mouse wheel: Multiple rapid clicks or fast wheel rotation
- Trackpad: Quick two-finger flick gestures
- Keyboard: Page Up key or rapid arrow key presses
- Touch devices: Fast flick or swipe gestures
🎪 Power user pattern: High thresholds appeal to users who prefer keyboard shortcuts and fast navigation - they'll naturally scroll with the required speed.
📱 Cross-Device Behavior
How high threshold feels across different devices:
- Desktop: Requires deliberate mouse wheel acceleration or keyboard navigation
- Laptop: Two-finger trackpad flick gestures work naturally
- Touch devices: Fast swipe gestures - matches mobile app expectations
- Accessibility tools: May require configuration for some assistive devices
⚖️ Trade-offs to Consider
High thresholds provide benefits with some trade-offs:
✅ Benefits
- Minimal UI distraction
- Focus on content consumption
- Clean, professional aesthetic
- Matches mobile app patterns
- Appeals to power users
⚠️ Considerations
- Less accessible for some users
- May frustrate casual browsers
- Requires user education/discovery
- Not ideal for complex navigation
- May need accessibility alternatives
The key is knowing your audience. High thresholds work beautifully for focused, content-centric experiences where navigation is secondary to consumption.
Try the fast scrolling motions now - notice how the header only appears when you demonstrate clear intent to navigate. This creates a calm, focused browsing experience that stays out of your way until you need it.
Even with high thresholds, when the header does appear, it moves naturally with your scroll speed. The naturalness of the movement remains consistent - only the activation requirement changes.
