Yesterday I featured a site that many of my readers might find annoying—a side-scrolling or horizontally scrolling website. Instead of moving up and down through the browser, this site moves left to right. While I don't think this is a good idea for 95% of websites out there, when it is appropriate it can be jarringly fun. Have you ever created a horizontally scrolling website? If yes, how did it work out? Did your customers like it? If not, why not? Lack of opportunity, or do you hate horizontally scrolling websites?
