### CSS

- The {{cssxref("color_value/contrast-color()")}} [CSS function](/en-US/docs/Web/CSS/Reference/Values/Functions) is now supported. This function takes a {{cssxref("color_value","color")}} value and returns a contrasting color that ensures at least [WCAG AA minimum contrast](https://w3c.github.io/wcag/guidelines/22/#contrast-minimum).
- The {{cssxref("color_value/contrast-color()")}} function is now supported. This function takes a [`<color>`](/en-US/docs/Web/CSS/Reference/Values/color_value) value and returns a contrasting color that ensures at least [WCAG AA minimum contrast](https://w3c.github.io/wcag/guidelines/22/#contrast-minimum).
([Firefox bug 1682439](https://bugzil.la/1682439)).

- The {{cssxref("text-decoration-inset")}} property is now supported, which enables adjusting the start and end points of an element's {{cssxref("text-decoration")}} so it can be shortened, lengthened, or have its position shifted with respect to the rendered text.
- The [`<color>`](/en-US/docs/Web/CSS/Reference/Values/color_value) data type now supports the `display-p3-linear` color space. This space is similar to [`display-p3`](/en-US/docs/Glossary/Color_space#display-p3), except that it uses a linear-light transfer function and has no gamma-encoding, which allows for a higher precision in the colors displayed.
([Firefox bug 1996318](https://bugzil.la/1996318)).

- The [`text-decoration-inset`](/en-US/docs/Web/CSS/Reference/Properties/text-decoration-inset) property is now supported, which enables adjusting the start and end points of an element's {{cssxref("text-decoration")}} so it can be shortened, lengthened, or have its position shifted with respect to the rendered text.
([Firefox bug 1979915](https://bugzil.la/1979915), [Firefox bug 1997157](https://bugzil.la/1997157), [Firefox bug 1993043](https://bugzil.la/1993043)).

- The {{cssxref("@scope")}} [at-rule](/en-US/docs/Web/CSS/Guides/Syntax/At-rules) is now supported by default. This enables you to select elements in specific DOM subtrees, targeting elements precisely without writing overly-specific selectors that are hard to override, and without coupling your selectors too tightly to the DOM structure.
