Progressive enhancement

Definition

Progressive enhancement is a web development strategy that emphasizes building a basic level of user experience that works for everyone, while adding more advanced features for users with better browsers or devices. This approach ensures that the fundamental content and functionality are accessible to all users, regardless of their technology, while progressively enhancing the experience for those who can support it. This strategy supports both accessibility and adaptability across various platforms and devices.

Review Questions

• How does progressive enhancement improve accessibility for users with varying levels of technology?
  • Progressive enhancement improves accessibility by ensuring that all users can access essential content and functionality, regardless of their device's capabilities. By first building a basic version of the website that functions properly without advanced features, developers cater to users on older or less capable devices. Then, additional features can be added for those with modern technology, ensuring an optimal experience without excluding anyone.
• Compare progressive enhancement and graceful degradation in web design practices and discuss their implications on user experience.
  • Progressive enhancement and graceful degradation are two contrasting strategies in web design. Progressive enhancement begins with a solid foundation that prioritizes essential content for all users while layering advanced features for those with better technology. In contrast, graceful degradation starts with a fully featured site, which may lose functionality in less capable environments. The implication is that progressive enhancement creates a more universally accessible experience while graceful degradation might risk alienating users who cannot utilize more advanced features.
• Evaluate the long-term benefits of implementing progressive enhancement in web development for businesses aiming at sustainability and cross-platform compatibility.
  • Implementing progressive enhancement offers numerous long-term benefits for businesses, particularly regarding sustainability and cross-platform compatibility.
