PROFILE

Arne Köhn

Worked on the acl-org/acl-anthology repository to deliver a comprehensive front-end migration to Bootstrap 5, focusing on modernizing the user interface and improving accessibility. The project involved updating SCSS and CSS to enhance responsiveness, styling consistency, and cross-device usability while minimizing disruptions to existing workflows. Addressed layout and formatting regressions introduced during migration, such as whitespace and spacing issues, and implemented accessibility improvements like aria-labels for icon-only controls. Collaborated closely with other contributors through disciplined code reviews and co-authored commits, and updated documentation to reflect new workflows and assets, resulting in a more maintainable and efficient front-end codebase.
