Description

Verbatims of @MaximeTonnerre

Release not
- The specific component “On colored bg” has been split into two distinct components:
- A public version offering traditional management of dark and light modes
- A private version (allowing the core team to nest the component with other components) offering customized mode management with four possible configurations:
- Always in light mode
- Always in dark mode
- Light to dark mode
- Dark to light mode
- Consequently, for the private version, the name of the “Inverted color” variant has been replaced to “Mode control”.
