How do I address flexbox alignment differences across different browsers?

Example Concept: Flexbox is a CSS layout module that provides a more efficient way to lay out, align, and distribute space among items in a container, even when their size is unknown. To address alignment differences across browsers, use vendor prefixes like "-webkit-" for older versions of browsers, and test your layout in multiple browsers to identify and fix inconsistencies. Additionally, consider using tools like Autoprefixer to automate prefixing.
