How to create a navigation bar that will changes position in every page? I means, in homepage the position is at the bottom, then when we click another link, open another page, the position will change to the top. But, I will show using slide in / slide out effects. which we can see the movement from top to bottom and so on. just like this page : agencexy.com. and it also responsive. Is it possible to be done only by using CSS? Help me.
