Better fluid sizing with round()

This article explains how the CSS round() function can be combined with clamp() and container query units to achieve more predictable fluid sizing. It addresses the problem of inconsistent computed values (e.g., 19.7px) and demonstrates how round() snaps values to a specified step (e.g., nearest 2px). The article includes interactive demos for typography, spacing, and card components, showing practical use cases for improving layout rhythm and design consistency.
