Hi students,
this is the solution of the Codecademy task "ChorDoor": https://www.codecademy.com/paths/web-development/tracks/build-interactive-websites/modules/web-dev-interactive-websites/projects/chore-door
Unfortunately it is not so easy to follow the 70 steps in the video that Codecademy offers on YouTube as a help: https://www.youtube.com/watch?v=rlTvLTaZvBY
So if someone stucks and wants to compare the source code at the end, feel free...
