Berry Straver contributed to the nl-design-system/rijkshuisstijl-community repository by delivering a Language Navigation Accessibility Enhancement focused on improving WCAG compliance and readability for multilingual users. Using CSS and SCSS, Berry updated the selected background color in the language switcher to #2244, increasing contrast and supporting better accessibility across locales. The enhancement was implemented in a single, focused commit with co-authorship, reflecting a targeted approach to front end development and accessibility. While the work addressed a specific feature rather than a broad set of changes, it strengthened the design system’s foundation for future localization and accessibility improvements in multi-language contexts.
