Worked on the osism/osismhub.io.git repository to enhance user interface styling and ensure theme consistency across documentation and the OSISM hub. Focused on refining CSS hover states and improving dark mode responsiveness, resulting in a more cohesive and accessible user experience. Streamlined the Docusaurus UI by removing the image zoom plugin and simplifying the navbar configuration, which reduced visual clutter and configuration complexity. Applied CSS and JavaScript to standardize styling practices, minimize UI regressions, and lower maintenance overhead. The work emphasized maintainable front end development, supporting faster onboarding and a consistent look and feel across multiple platforms without introducing new bugs.
