Jan 1, 2025January 2025 monthly summary for ProjectSidewalk/SidewalkWebpage: This month focused on stabilizing the map legend UI to ensure consistent labelmap rendering across browsers, with a key emphasis on Firefox. A Firefox-specific rendering discrepancy was resolved by converting the labelmap circle coordinates from fixed pixel values to percentage-based values, centering the circle within the map legend container. This directly improves visual accuracy and user trust for map-based features. Technical changes were implemented in the SidewalkWebpage repository and tracked under commit 67ce91437d7b986dcfdd67a2222fddfe615312cc, with the message 'resolved issues with labelmap in firefox due to circle css'.
