技术细节
Tracking is a foundational concept in visual design theory. It influences how users perceive and interact with interfaces, affecting readability, hierarchy, and aesthetic appeal. The design principles behind tracking are codified in systems like Material Design 3, Apple's Human Interface Guidelines, and the W3C's Web Content Accessibility Guidelines. Implementing tracking correctly requires balancing aesthetic intent with accessibility requirements and cross-platform consistency.
