 ### CSS
 
-- The [`@container`](/en-US/docs/Web/CSS/Reference/At-rules/@container) CSS at-rule supports [`style()`](/en-US/docs/Web/CSS/Guides/Containment/Container_size_and_style_queries#container_style_queries) queries. This allows you to check if a container has a valid CSS declaration, a CSS property, or a custom property, and apply styles to its children accordingly. ([Firefox bug 2016929](https://bugzil.la/2016929)), ([Firefox bug 2019254](https://bugzil.la/2019254)), ([Firefox bug 2024601](https://bugzil.la/2024601)), [Firefox bug 2030645](https://bugzil.la/2030645)).

+- The {{cssxref("position-anchor")}} CSS property now supports the `normal` (default) value. This allows the matching of the {{cssxref("position-area")}} property, so if the `position-area` property updates the `position-anchor` property will also.
