Better Anchor Positioning with position-area

This article dives into the new position-area CSS property, which seems like a simple shorthand at first but actually introduces new behaviors for positioning elements. Unlike the traditional anchor() method, position-area creates a unique containing block defined by the relationship with its anchor, allowing for more intuitive and precise placements around specific corners or edges. It smartly shifts to prevent overflow, ensuring elements stay within their intended area.

Reducing CSS complexity with the :is() pseudo-class

The author shares their recent experience using :is() to tidy up a tangled web of CSS rules, transforming what was once an overwhelming mess into something much more manageable and readable. It also touches on the benefits of :is() over CSS nesting, particularly noting its superior browser compatibility. There's a small caveat about specificity to keep in mind, but overall, this piece does a fantastic job of illustrating how :is() can streamline your CSS workflow and reduce selector complexity.
