Can you explain the difference between progressive improvement and graceful degradation?

Progressive Enhancement starts with basic functionality for a wide range of devices and browsers, then adds more advanced features for supporting environments. Focus on accessibility and a basic experience for all.

Graceful Degradation begins with full functionality for modern browsers. For older or less capable environments, alternatives or simplified versions are provided, aiming to maintain operability but potentially losing some features. Focus on providing the best experience for most users.

	Starting Point	Focus	Approach to Older Browsers
Progressive Enhancement	Basic functionality for everyone	Accessibility, universality, core	Additional features for supporting environments
Graceful Degradation	Full functionality for modern browsers	Better experience for most, advanced technologies	Backup options are provided
