Scrollbar with points
Can someone explain to me (or has a good tutorial for it) how this scrolling thing works? I don't know how I should google it.

This looks like a side scrollbar, and when I scroll down, it switches one Point down, and the page changes. Are there thew tutorials on how to create this? Please send me some info about it, because I really wanna know how to create this.

https://developer.mozilla.org/en-US/docs/Web/API/Element/scrollIntoView

They speak about:

.scrollTo

scroll-behavior

scrollIntoView()

scrollIntoView(alignToTop)

scrollIntoView(scrollIntoViewOptions)
