Hi, this is an example post. This is #3. If you look at the sample code, you will see this is set as the last poste in hashbloge.js's const lastPost. When the user visits /blog, the last poste is the default poste shown.
I am going to put a long image below so you can see how the page automatically scrolls to top once you go to a new poste.

(It's a panel from my comic :) )
Press "Older" below to see another sample post, and you'll also see how the bloge scrolls back to the top.
