Styles, templates, triggers, and storyboards in WPF allow for a consistent and shared appearance within and across applications. Styles define a set of properties that can be applied to multiple elements, enabling centralized management of designs. Templates replace parts of controls and reduce custom control needs. Triggers modify properties or start animations based on conditions. Resource dictionaries package UI resources as reusable themes.
