Understanding Progressive Enhancement
Progressive Enhancement is a web design strategy that focuses on building a basic, functional experience first, and then adding more advanced features for browsers and devices that support them. This ensures accessibility, usability, and broader compatibility.
Core Principles of Progressive Enhancement
- **Start with content:** Ensure the basic information is available using plain HTML so that all users, regardless of browser or device, can access it.
 - **Add style with CSS:** Enhance the presentation with CSS for users with modern browsers, without breaking functionality for others.
 - **Layer interactivity with JavaScript:** Introduce advanced features or behaviors through JavaScript, but the site should still function if scripts fail or are disabled.
 - **Graceful fallback:** Provide alternative experiences so that older browsers or assistive technologies can still use the site effectively.
 
Example of Progressive Enhancement
In short: Progressive Enhancement ensures that your website works for everyone at a basic level and gets better for users with modern browsers and devices.
