I'll create a collapsible sticky header using React that shrinks to a minimum height of 20px when the user scrolls down. The content will adjust its position to stay below the header until it reaches the minimum height. After that, the content will scroll behind the header. Let's implement this using React and some CSS transitions for a smooth effect.

Let's create the components:

This implementation creates a collapsible sticky header that shrinks to 20px (5 in Tailwind units) when the user scrolls down. Here's how it works:

1. The Header component uses the useEffect hook to add a scroll event listener. It updates the isScrolled state based on whether the user has scrolled or not.
2. The header's height is controlled by Tailwind classes. It starts at h-20 (80px) and shrinks to h-5 (20px) when scrolled.
3. The text inside the header also shrinks using a CSS transition for a smooth effect.
4. The Content component has a top padding (pt-24) to ensure it starts below the expanded header.
5. As the user scrolls, the content will stay below the header until it reaches its minimum height of 20px. After that, the content will scroll behind the header.
6. The z-50 class on the header ensures it stays on top of the content.
7. The transitions are handled by Tailwind's transition-all duration-300 ease-in-out classes for a smooth animation effect.

This implementation provides a smooth, collapsible sticky header that shrinks to a minimum height of 20px as the user scrolls, with the content adjusting its position accordingly. You can further customize the colors, sizes, and content to fit your specific needs.

I apologize for the misunderstanding. You're right, we need to implement a more dynamic shrinking effect based on the scroll amount. Let's modify our implementation to achieve this behavior. We'll use a custom calculation to determine the header height based on the scroll position, and we'll adjust the content's position accordingly.

Here's the updated implementation:

This updated implementation provides a dynamic shrinking header that adjusts its height based on the scroll position. Here's how it works:

1. We define constants for the maximum height, minimum height, and scroll threshold.
2. The Home component now manages the headerHeight state and passes it to both the Header and Content components.
3. The scroll event listener calculates the new header height based on the scroll position. It uses a linear interpolation between the max and min heights over the defined scroll threshold.
4. The Header component now uses an inline style to set its height dynamically. The font size of the header text is also adjusted proportionally.
5. The Content component receives the headerHeight as a prop and uses it to set its top padding. This ensures that the content always starts just below the header, regardless of its current height.
6. We've reduced the transition duration to 100ms for a more responsive feel, but you can adjust this as needed.
7. The content will not go behind the header until it reaches the minimum height of 20px.

This implementation provides a smooth, dynamically shrinking header that adjusts its height based on the scroll position. The main content always stays below the header until it reaches its minimum height of 20px. You can further customize the colors, sizes, and content to fit your specific needs.
