What is the difference between using @keyframes and transitions for creating animations in CSS?
- @keyframes are used for simple one-step animations, while transitions handle multi-step animations.
- @keyframes define the intermediate stages of the animation, while transitions only specify the start and end.
- Transitions and @keyframes can be used interchangeably for any animation.
- Transitions are more suitable for complex animations with multiple stages.
@keyframes allow specifying keyframes at various points during the animation, enabling complex multi-step animations. Transitions are simpler and are generally used for basic animations with a start and end state.

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 is more flexible for rearranging elements based on screen size because it is designed for two-dimensional layouts.
