# Key Differences Between Flat UI and Milligram

Flat UI and Milligram are two popular CSS frameworks used for web development, each offering unique features and design principles. Below are the key differences between these two frameworks:

1. **Design Philosophy**: Flat UI follows a minimalistic design approach with a focus on simplicity, while Milligram emphasizes a more opinionated design language, providing a set of predefined styles for rapid development. 
   
2. **Customizability**: Flat UI offers more customization options, allowing developers to tailor the design according to their needs, whereas Milligram comes with a default set of styles that are less customizable but faster to implement.

3. **File Size**: Milligram has a smaller file size compared to Flat UI, making it a more lightweight option for projects where performance is crucial.

4. **Component Libraries**: Flat UI provides a wider range of pre-built components and utilities, while Milligram is more focused on providing a simple foundation for styling, requiring developers to build additional components themselves.

5. **Compatibility**: Flat UI is compatible with a wider range of browsers, ensuring a consistent experience across different platforms, whereas Milligram may require additional polyfills for full compatibility.

6. **Learning Curve**: Milligram has a steeper learning curve compared to Flat UI due to its opinionated design choices and limited customization options, making it more suitable for developers who prefer a more prescriptive framework.

In Summary, the key differences between Flat UI and Milligram lie in their design philosophies, customizability, file size, component libraries, compatibility, and learning curve.
