How to make block pagination on the page?

Question

css

Hello.
How to make a similar pagination (right middle).
What is in the screenshot is FullPage.js, but the library is not suitable because it is not flexible, another solution is needed.
Thank you.

Answer 1

It's all right?

<div style="position: fixed; right:0; top:50%;">
<a href="#block1">иконка</a>
<a href="#block2">иконка</a>
<a href="#block3">иконка</a>
</div>

Answer 2

Well, how should this one differ from this inappropriate inflexible one?
