This document discusses best practices and challenges for designing and developing websites. It separates topics into those that are considered "good" and "bad" practices. "Good" practices include organizing layers in Photoshop files, using transparent images over opaque ones, pre-cutting files for developers, including screenshots of page layouts, and using web-friendly fonts. "Bad" practices include focusing too much on pixel perfection instead of scalability, relying only on image-based elements rather than CSS3, having sloppy CSS rather than organized CSS, and using static HTML over a content management system.
