During March 2026, work focused on resolving a targeted user interface issue in the CollaboraOnline/online repository. The primary contribution involved fixing a rendering bug affecting the view mode dropdown on iOS devices, which previously caused inconsistent width display across platforms. By leveraging CSS and front end development skills, the solution introduced precise adjustments to width handling, ensuring a more consistent and reliable user experience for iOS users. The fix was committed and reviewed in the main branch, demonstrating attention to cross-device compatibility and detail-oriented problem solving. This work utilized CSS as the main language and addressed a specific usability concern.
