Oleksandr Khokhuli enhanced the Manual Collection feature in the OCIOStateOfNebraska/stateofnebraska-aem repository by increasing image sizes for improved visual presentation on medium and larger viewports. He introduced a new CSS class and updated existing SCSS styles to ensure consistent application of the enhancement across the UI. The work was delivered through two targeted commits, focusing on front-end development and responsive design. While the project scope was limited to a single feature and did not involve bug fixes, Oleksandr’s contribution addressed a specific UI need, demonstrating proficiency in CSS and SCSS for targeted, maintainable interface improvements within a short timeframe.
