July 2026: Delivered targeted improvements to CSS rendering and styling precision across MDN repos. In mdn/content, introduced length snapping to a line width for CSS styling and added documentation clarifying how computed lengths are rounded, enhancing developer understanding. In mdn/data, updated computed values for border/column-rule/outline-width and outline-offset to improve rendering accuracy and simplified descriptions, removing unused values. These changes improve visual consistency, reduce support overhead, and demonstrate strong collaboration, lint CI hygiene, and documentation quality.

June 2026 delivered a focused CSS documentation refactor in mdn/content to clarify the relationships between border, column-rule, and outline-width, removing these properties from the *-style property group and reducing ambiguity for CSS authors and readers.
