Worked on the FabricMC/fabric-docs repository to address a user interface issue affecting image overlays. Focused on front end development using CSS, the developer implemented a targeted z-index adjustment to the medium-zoom overlay, ensuring that opened images consistently render above other page elements. This fix resolved persistent layering problems and eliminated visual glitches that previously disrupted the documentation experience. The solution was validated through targeted testing and code review, minimizing the risk of regression. By refining the overlay behavior, the developer improved the overall user experience and maintained consistent image rendering across documentation pages, demonstrating attention to detail in CSS implementation.
