'How to implement scroll & card-stack like animation in React / TailwindCSS?

I want to implement scrolling animations like below in React & Nextjs (and I am using TailwindCSS)

Not sure how to explain this effect (scroll -> stack -> appear), but the user scroll down, and the next part shows up in a fixed place. Then, once it scrolls to a certain point, it starts moving.

I assume it is a combination of the z-index but not sure how to implement it.

Example

Here is the above site I found and want to know how to achieve this kind of scrolling effect.

Solution 1:[1]

It is done with the help of position: sticky; at block two class="s-heading-first".

.section.s-heading-first {
    position: -webkit-sticky;
    position: sticky;
    bottom: 0%;
    display: flex;
    padding-top: 27rem;
    padding-bottom: 1rem;
    -webkit-box-orient: vertical;
    -webkit-box-direction: normal;
    flex-direction: column;
    -webkit-box-pack: end;
    justify-content: flex-end;
}

I think that can help you.
