Some pages in Extend contain a single article, graphic, or other item. Usually, you see these pages because you click a link on a main page to open them.
But those main pages might contain lots of different articles, or pieces of articles. They could also have images, links to sound or video files, etc.
All of the articles, images, and other media on these main (or channel) pages are know collectively as "content". Extend organizes content on pages into "content areas". The topics in this section explain how to organize these content areas and change their appearance.
