Worked on the kubex/zinc repository to enhance visual stability in dynamic user interfaces by introducing a new CSS utility class, .visibility-hidden. This feature allows elements to be hidden without causing layout shifts, ensuring that hidden elements still occupy their intended space in the document flow. The approach focused on improving user experience during UI updates by addressing layout consistency issues. Leveraging CSS and front-end development skills, the implementation included a base visibility style and was closely aligned with issue tracking for traceability and quality assurance. The work demonstrates attention to detail in UI behavior and a methodical approach to front-end engineering.
