This document discusses good and bad design practices for SharePoint and Office 365 sites. It covers choosing color palettes, fonts, page layouts, and effective ways to present links and navigation. For colors, it recommends using a limited palette and pairing warm and cool tones. For fonts, it suggests choosing pairs of complementary fonts and proper sizing. Common page layouts include top zone, two-column, and three-column designs. Effective navigation uses drop-down menus, mega-menus, vertical styles and limits the number of links. The goal is to make content easily digestible and navigation simple to use.
