Include Html in Jupyter notebook

I just discovered something that is great and simple at the same time... how to include html in the Jupyter notebook.
As I want to create easily graphic content for different purposes (and you see in the last post what I mean) I find it just... sensational... or is it just me?

So, I will make a short example, as I am used to do... and lately we sill make something more complicated, maybe.

Ok... go in the cmd and write

jupyter notebook

or 

ipython notebook

create a notebook and write this in a cell

%%%html

<button onclick="alert('Ciao')">Ciao</button>

There we go! We have a button... it's all in html! And the button works. Isn't it great?

See ya.
