When you download the exercise files, there's going to be five folders inside of there. If you're a Premium subscriber to the lynda.com online training library, you'll have access to all five folders. If not, you'll have access to folders 1, 2, and 4. These are the minimum number of files that you'll need to complete the course. Inside of folder 1 is Files to add. This is going to give us a series of blank CSS files and a mostly empty HTML file. I provided these just to make sure we're all working from valid HTML and CSS files. Inside of folder 2 is a Skip Photoshop folder.
