Developed a dark theme with a color scheme toggle for the spacelift-io/user-documentation repository, focusing on enhancing documentation usability and accessibility. The work involved updating CSS and configuring MkDocs to support seamless switching between light and dark modes, allowing users to adjust the interface for different lighting environments. By centralizing theming logic, the changes reduced cognitive load for readers and simplified future maintenance. The approach emphasized clear traceability and a low-risk scope, ensuring stable integration. Skills applied included front end development and documentation, with CSS and YAML as primary technologies. No major bugs were addressed during this period, reflecting focused feature delivery.
