Hi Jack,
Thanks for your quick reply, for sure it'll be really helpful for me, I'll follow your advice step by step.
For the third point, It was midnight in my country, I just copied the code I has in my editor without any update ^^, I understand for "scrub" and "toggleActions" now that you said that, it's clear that they're exclusive.
For the fourth point, the effect I want to achieve is having the pin moving down until he reaches the top of the car then pinning the whole section ( Car and text ) + the pin which isn't a part of the second section, don't know if my approach is the best way to get the effect done.
What about the approach I should use in end/start? It will be beneficial to use px or should I replace that to get the correct effect in all the breakpoint?
