[HELP] What is the code for this positioning?

Hi,

I'm not a programmer, I just know basic html, but I am wondering how to create a simple page using the same positioning of the Google Ads in this page:

Yes, it is another language but I am only intereste in the code.

The Google Ads block I'm referring to is the second one, on the right side, after "Add a Comment".

That ad block remains on the same place when we scroll down the page after the blocks above it. However, it does not get "over" aniything, then not blocking the view of other content. It seems elegant and useful.

Yes, I looked at the code on that page but it is so nested within so many things that I could not understand. As I said, I'm not a programmer.

Could anyone help me with the html code to create a simple html page like that?


Thanks in advance.

Would appreciate if anyone could help.
