Endless layers in Photoshop. Overstuffed image folders. That jQuery plug-in that has 12 files associated with it. Hundreds or thousands of individual pieces go into making a website. No wonder we go off the deep end when we can’t find a closing div — er, section tag. We work with a ridiculously large number of things, and how we organize them (or choose not to) is often left to personal preference. But our messy habits result in confusion for the designer or developer who inherits your work.
