How to make a site look similar to the following

I noticed that a lot of modern sites' home pages have a unique look and feel.  As opposed to being one content area, it appears that they attempt to bundle several pages of content into one page.  As you scroll down the page, more and more things appears.  How is this done?  What framework or content management system is used for this?  Thanks!  Some examples can be seen in the following:

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Another example is the following:

It appears that these pages are built to be tall or long.  How can I find instructions on how to duplicate such a page?

At a basic level those websites are achieved by using multiple containers stacked on top of each other to create the long look of the website. It's like adding paragraphs to a word file - the document grows down with the more you add and users have to scroll down to view the additional information.

Some of the sites make use of javascript and css/html5 to include additional functionality to the areas (such as floating menus, dynamic content and the like) but the fundemental construction is pretty much the same.

Looking at the source code is a good start to understanding how these work as you'll see the common factors involved.
