how to make link in onepage website

hi, Sorry if my question so newbie :) because I just use BSS in few days , if anyone can help me how to link each navbar to next page thank you so much. . .

You need to add an id to each section you want to anchor too and the in the nav your links will be #<yourIDName>

So If I have a section an id of 'about' then my link will be #about

See this site I built for my uncle which is a one page website: hackwoodfabricatedsolutions.co.uk
