Deference to content principle

Content should take center stage in every interface. Apple's principle of deference means UI elements support rather than compete with content. When interface elements defer to content, they guide users' attention to what matters most without drawing attention to themselves. Interface elements should feel transparent to users, both visually and cognitively.

Apple Music's now playing screen exemplifies this — album artwork dominates the view while playback controls remain easily accessible but visually subtle. The controls use translucent backgrounds and minimal contrast, appearing when needed without overshadowing the artwork. The background color adapts to the artwork but stays muted, creating a cohesive yet understated environment. This balance ensures users focus on what matters while maintaining effortless control.
