Hi mayari79
1 - This template is built with T4 which utilizes BS4, pls check out this docs for hiding elements: https://getbootstrap.com/docs/4.0/utilities/display/#hiding-elements
2 - I don't get your point here, could you share screenshots illustrating the issue?
3 - You can set it via layout settings of template in: Admin panel > Extensions > Templates > JA Event Camp template style > Layouts Settings > select settings for Header section and set Sticky for it: https://prnt.sc/t9hw8c
