Joomla 4 templates - Book / Livre

Pardon, je me suis mal exprimé peut-être. Dans ton livre tu utilises Bootsrtap 5 pour la création d'un template ? Et est-ce qu'il y a une partie création backend pour des régales couleurs par exemple ?

non je n'utise pas Bootstrap 5 dans mon livre
Il y a un exemple de création d'option dans le backend du template, pour controler la couleur de fond du template par exemple

Greetings.
Is this book still relevant? Since joomla 5.2 has already been released. And were there any updates and additions after the publication of the first version of the book?

Hi
the book is still relevant because the methods are the same between joomla 4 and 5 for the templates
I have already added the child templates feature as appendix

I have not updated the book title because it needs some time

if you have some questions, do not hesitate to ask here

Using this book, is it possible to make a template for joomla 5 from a ready-made html and bootstrap 5 template?

Are there any plans to update this book in the near future?
