Hello everyone,
I finished the Product Landing Page challenge, I would like to request your feedback.

If you find any bugs, or something what can be improved feel free to tell me 
The application is only optimized currently for tablet size, I still plan to do the mobile phone media queries.
I think the design can still be improved, I plan to create a smooth navigation effect with pure VanillaJs later on.
Currently what I noticed is that the site is jumping around when I click on the navigation. I plan to fix that as well.
Thank you!
Best Regards,
Gabor
