Seriously thinking of buying this book: https://korban.net/elm/book/

@SimonLab Qu'est-ce que tu penses ?

The most interesting aspect are the ones linked UI and css but it's also always good to refresh and read other explanation for topic we are already comfortable with.
Also money back guarantee if not happy.

Hi @alexkorban thanks for letting us know that the download link isn’t single use. 🙃
We didn’t mean to share it, rather it was for personal use as a “note to self” reminder to send the kindle version to myself.
Thanks again for the great content! Keep up the superb work! 👍🏻
