-### Relative color syntax
-
-[Relative color syntax](/en-US/docs/Web/CSS/CSS_colors/Relative_colors) is now enabled by default in the Nightly release and via the `layout.css.relative-color-syntax.enabled` preference set to `true` in other release versions. Relative color syntax allows you to create a color value relative to an origin color, and can allow you to change a color in a different [color space](/en-US/docs/Glossary/Color_space) using [color functions](/en-US/docs/Web/CSS/CSS_colors#functions) ([Firefox bug 1701488](https://bugzil.la/1701488)).

### CSS
+- [Relative color syntax](/en-US/docs/Web/CSS/CSS_colors/Relative_colors) is now enabled by default. Relative color syntax allows you to create a color value relative to an origin color, and can allow you to change a color in a different [color space](/en-US/docs/Glossary/Color_space) using [color functions](/en-US/docs/Web/CSS/CSS_colors#functions) ([Firefox bug 1900251](https://bugzil.la/1900251)).
- The [`content`](/en-US/docs/Web/CSS/content) property now supports [alternative text](/en-US/docs/Web/CSS/content#alternative_text) for content that includes an image. The alternative text is then exposed to the browsers accessibility tree. (See [Firefox bug 1281158](https://bugzil.la/1281158) and [Firefox bug 1896047](https://bugzil.la/1896047)).
