Im setting up a new site and trying to learn CSS. Ive been looking at professionally done sites, and I noticed that when they link to their pages (Home, about, products, etc)... I see that they simply go to a folder created there rather than about.htm or something. So when you click about it might go to www.asdf.com/about To do this I simply create a folder for each link and then put an index.html file in there? Second question... Say I have index.html for the Home page (with news and all that jazz), and then I have an about me section. I assume that theres no easy way to change all of the parts on all the pages at once.. say I want to remove one of the links (or change "about" to "about me"),... then i would have to go to each folder respectively, open the index.html file, and then make those changes? Its not a big deal.. but im wondering how bigger sites manage this because i feel like that would get really complicated.
