Usage Recommendations

Background Selection Principles

1. Coordinate with Theme: Background should match overall color scheme
2. Avoid Interference: Should not affect readability of text and interface elements
3. Performance Consideration: Large images may impact loading performance
4. User Experience: Background should enhance rather than interfere with user operations

Recommendations by Type

• Solid Color Background: Clean, good performance, suitable for most scenarios
• Gradient Background: Modern feel, suitable for users pursuing visual effects
• Image Background: Highly personalized, but pay attention to contrast and performance

Common Issues to Avoid

1. Insufficient Contrast: Dark backgrounds with light text, light backgrounds with dark text
2. Overly Complex Images: Avoid background images with too many details that affect reading
3. Color Conflicts: Ensure background coordinates harmoniously with theme colors
