How to make an interactive navigation that will unlock ex. lesson 2 if done with lesson 1? It's like creating progress.

Answer 1

if (!finish = true) {
continue lesson
} else {
unlock next lesson
}

Answer 2

- of course you can.
- you insert it in <script> </script> tags
- you can link it directly (so when the user click on it to be transferred to your link) or try a "target:_blank" to open in a new window.

Answer 3
