Which icon font library is best for responsive design, Font Awesome or Material Icons?

Both Font Awesome and Material Icons are well-suited for responsive design, but they have different strengths:

Font Awesome:
- Scalability: Font Awesome icons are scalable by adjusting the font-size property, which is perfect for responsive designs.
- Variety: Offers a wider range of icons, which can be more versatile for different projects.
- Customization: Easily customizable with CSS, allowing for responsive adjustments to size, color, and even animations.
- Accessibility: Provides built-in classes for better screen reader support, enhancing responsive accessibility.
Material Icons:
- Consistency: Designed to be part of Google's Material Design, ensuring a consistent look across devices, which is ideal for responsive layouts.
- Integration: Seamlessly integrates with other Material Design components, making it easier to create a uniform responsive design.
- Scalability: Like Font Awesome, Material Icons are also scalable via font-size, fitting well into responsive designs.

However, if your project follows Material Design principles and you value a cohesive design system, Material Icons would be more suitable.
