Verbeteren website front-side (Bootstrap Menu + Script voor vergroten foto 'onclick')

Dear freelancer, Description (if needed available in Dutch=my native language) The website is built and fully operational in a Laraval/Blade stack. The front-end is done by a Laraval developer, the lay-out is done by me. For this I need help: I have 1 issue I cannot solve + I would like to have 1 improvement to the website. The issue: my bootstrap menu is 'jumping' on mobile devices when opening The menu is folded on smaller mobile devices, taken care of with Bootstrap. But when unfolding the menu, the menu is jumping to the left (linked to padding? Margins?) and causing a bad lay-out. The needed improvement: enlarge pictures on 2 different pages by clicking on the picture I tried some Modal in Bootstrap + Javascript coding, but this didn't work out properly. By clicking on the picture, I would like to have this enlarged to full screen. And by clicking outside the picture or on the 'X' the full screen viewer should close. What's provided o Website app is built and 100% functional o Framework: Laravel and Blade + MySQL database o Workflow available in GitHub Preferred framework/stack o Client side: Bootstrap + Javascipt/JQuery I think this is a small project for an experienced Bootstrap/JS developer. Intrerested? Leave a comment below!
