Fundamentally, progressive enhancement is about accessibility, but not in the limited sense the term is most often used. The term "accessibility" is traditionally used to denote making content available to individuals with "special needs" (people with limited mobility, cognitive disabilities, or visual impairments); progressive enhancement takes this one step further by recognizing that we all have special needs. Our special needs may also change over time and within different contexts. When I load up a website on my phone, for example, I am visually limited by my screen resolution (especially if I am using a browser that encourages zooming) and I am limited in my ability to interact with buttons and links because I am browsing with my fingertips, which are far larger and less precise than a mouse cursor.
