Preview

Simulates a glassmorphic fixed navigator with scrolling. Click the button in the preview to see the scrolling effect.

Use cases and features

• Landing Page/Portfolio: The navigator’s expression changes as you scroll, giving it a well-crafted feel.

• Suitable for dark themes: Glassmorphism’s backdrop-filter: blur looks especially good on dark backgrounds.

• Utilizing position: sticky: Maximize performance by leveraging position: sticky in CSS instead of relying only on JavaScript.

Points of design and UX

1. Fires at scroll 10px: Glass morphism appears at neutral timing.

2. Change in padding: Reduced from 1.25rem to 0.75rem to make it more compact and secure a wider content area.

3. Smooth with transition: Create natural changes by simultaneously transitioning the four properties of background, blur, box-shadow, and padding.

How to customize

Change scroll start threshold:

// trigger earlier (5px)

if (demo.scrollTop > 5) { ... }



// trigger later (50px)

if (demo.scrollTop > 50) { ... }

add link:

<li><a href="#services">service</a></li>

<li><a href="#blog">Blog</a></li>
