In March 2025, Kattsoff developed a new design token for the VKCOM/vkui-tokens repository, enabling advanced calendar theming by introducing calendarColorSidebarItemBackground with support for both light and dark theme states. Using CSS, JavaScript, and TypeScript, Kattsoff defined normal, hover, and active background states for calendar sidebar items, ensuring consistent and accessible UI styling across themes. This work expanded the design token architecture, streamlining future branding updates and reducing styling overhead. The approach demonstrated a strong grasp of front-end development and theming, resulting in improved UI consistency and a more maintainable, token-driven customization path for the calendar component.
