Responsive Typography and Spacing Systems
Typography is responsible for 95% of web design, yet most responsive implementations handle it poorly — either jumping abruptly between sizes at breakpoints or staying static across all screens. In this lesson, you will learn to create fluid type scales that smoothly interpolate between sizes, producing a reading experience that feels intentional at every viewport width.

Key Concepts
- Fluid Typography: Using clamp() for smooth font-size scaling between breakpoints
- Modular Scales: Building typographic hierarchies with mathematical ratios
- Spacing Tokens: Creating consistent, responsive spacing with CSS custom properties
- Vertical Rhythm: Maintaining consistent line-height relationships across type sizes
Hands-On Exercise
Task: Create a fluid type system using CSS clamp() for headings (h1-h6) and body text. Define a spacing scale using CSS custom properties (–space-xs through –space-xl) that also uses clamp() for fluid spacing. Apply both to a sample blog post layout.
Pro Tips
The magic formula for fluid type is: clamp(min, preferred, max). For body text, try clamp(1rem, 0.9rem + 0.5vw, 1.25rem). For h1, try clamp(2rem, 1.5rem + 2.5vw, 4rem). These produce smooth scaling that feels natural.
