CSS Positioned Layout Module Level 3

The CSS Positioned Layout Module Level 3 is a comprehensive update that modernizes how elements are placed and layered on web pages. It preserves the core behaviors of CSS2.1 while introducing sticky positioning, which allows headers and navigation bars to remain visible during scrolling without requiring complex scripts. The module integrates traditional positioning with modern layout systems like Flexbox, Grid, and CSS Writing Modes, ensuring that alignment and logical offsets work seamlessly across different languages. Major browsers like Chrome, Firefox, and Safari have high implementation rates, though some minor discrepancies regarding fragmented inline elements and auto-margin calculations are still being refined. Beyond basic offsets, the specification clarifies how transformations and containment affect the coordinate system for fixed and absolute elements. This ongoing standardization effort aims to provide developers with a robust, high-performance toolkit for creating complex user interfaces that remain responsive and efficient.
