Sticky pages

Hi there,

I'm working on a website in developer mode. I used the 'sticky' property in order to make every page of the website stick to the top when scrolling. The problem I'm having is that when I scroll down the pages stick to the bottom on top of each other: when then I select any page from the nav bar it doesn't redirect me anywhere.

I hope this makes sense, thanks in advance for your help!
