Anchor positioning simplifies the process of placing elements on a webpage relative to other elements, allowing for responsive design using only CSS. By establishing a connection between an anchor (e.g., an avatar) and a target (e.g., a menu), developers can easily control the menu's position with properties like position-area and anchor(). This method enhances flexibility, especially for mobile views where space is limited.

CSS inline conditionals with the if() function are now available in Chrome 137, allowing developers to create cleaner, more dynamic styles using condition-value pairs. This function supports style, media, and supports queries, enabling streamlined inline logic for responsive designs and state-based styling. Future enhancements may include range querying and integration with custom functions in CSS.

A collection of CSS custom functions is available that utilizes the native CSS @function rule, requiring no build step for integration. Currently supported in Chrome 141+, it includes around 43 functions for various tasks, including math, color manipulation, typography, and layout, making CSS more efficient and streamlined for developers.
