Worked on the Kommunicate-Web-SDK repository to enhance the user experience of loading indicators by stabilizing spinner visibility and refining UI stacking. Focused on improving CSS specificity and class naming to ensure spinners consistently render above content, addressing issues with z-index and visual glitches. When a previous spinner fix introduced regressions, promptly reverted the change to restore stable behavior. Utilized CSS and HTML to polish the front-end interface, resulting in more reliable and visually coherent loading indicators. The work emphasized maintainability and future-proofing of styles, contributing to a smoother and more predictable user experience across the web SDK’s interface.
