Worked on the gravity-ui/navigation repository over a two-month period, focusing on front-end stability and documentation clarity. Addressed persistent horizontal overflow issues in the AsideHeader component by refining CSS, first introducing horizontal scrolling to prevent content cutoff, then removing unnecessary overflow to ensure consistent rendering across viewports. Improved documentation by renaming components in both English and Russian READMEs, aligning references with actual usage and aiding developer onboarding. Utilized SCSS and Markdown to implement these changes, emphasizing maintainable code and clear communication. The work prioritized usability, bug resolution, and accurate documentation, resulting in a more reliable and developer-friendly navigation interface.
