- 'column-start / row-start'

For a responsive web design that needs to rearrange elements based on screen size, which layout method (Flexbox or Grid) offers more flexibility in terms of row and column manipulation, and why?
- Both Flexbox and Grid
- Flexbox
- Grid
- Neither Flexbox nor Grid
Grid is more flexible for rearranging elements based on screen size because it is designed for two-dimensional layouts. It allows precise control over both rows and columns, making it easier to rearrange content dynamically. While Flexbox is excellent for one-dimensional layouts, Grid is better suited for complex and responsive designs involving both rows and columns.
