Worked on the contentful/experience-builder repository to address a cross-browser inconsistency affecting image placeholders in Safari and Firefox. Focused on improving UI reliability, the developer implemented a targeted CSS and React solution that removed the native missing image indicator and preserved the placeholder’s corner radius when images failed to load. This fix ensured visual consistency across browsers and enhanced the user experience without introducing regressions. The approach emphasized maintainability by limiting the scope of changes and leveraging front-end development best practices. The work demonstrated effective cross-browser debugging and a thoughtful application of CSS, React, and TypeScript to solve nuanced rendering issues.
