Scroll down to the last sections of the article.
You will find:
{
The replica
Getting back to the real code subject, to make things interesting, since we are on Medium, I will create a static replica of an imaginary Medium article webpage.

Followed by:
{
I CHALLENGE you, Children Of The Zen Garden,
to make a better replica than that!
In case any High Priest accepts the challenge, I will write here links to his/her article and replica.

I think the "Replica" section explains what you missed in the title and about real code.
And in the "I CHALENGE..." section, there is the invitation for the "contest".
I hope you can find this time.
