That’s a beautiful mobile site. But beauty is only skin deep. Under the covers, it’s a different thing entirely. It may look like a mobile site, but it’s still a desktop site in mobile clothing. If we want this site to be greased lightning on mobile, we need to start with mobile first. We’ll begin by dissecting the current site to find the desktop bones hiding in its mobile closet. We’ll clean house and start fresh with progressive enhancement, building from the basic content all the way to a desktop view. When we’re done, you’ll have a page that is optimized regardless of the screen size.
