Question

css

In general, the essence of the issue fit in the title.
If anyone has a similar experience (offline learning), please share your opinion, recommendations or advice. How to further interest students, which topics at the initial stage are better to bypass and leave for independent development, which ones must be touched upon. What textbooks to be guided by when compiling lessons. What are the pitfalls in such an undertaking. How much to devote to theory, how much practice. And other questions.
The goal of the entire campaign is to educate children and popularize it in the region.

landing page reasons:
1) many interesting and new solutions are mostly used in landing pages
2) complexity is well regulated simply by adding and removing screens (example: it needs to be more difficult for this student - insert a screen with an unusual slider, etc.)
3) easy to google landing page designs
