Modular Scale

Pollen provides a robust modular typography scale to encourage consistent typography sizing across an interface. Sizes are set in rem units to support proper font scaling, and assume a 16px root font-size.

Fluid Modular Scale

In addition to the standard modular typographic scale above, Pollen also comes with a fluid scale that tweens between steps on the scale as screen width changes. Its built with Pollen's own fluid utility, which generates complex CSS clamp() functions based on screen width bounds.
Each fluid font size resizes between a min and max size, starting at mobile screen sizes (480px) and ending at normal desktop screen sizes (1280px).
