How does the order property affect flex items?

Q: How does the order property affect flex items?

The `order` property in CSS controls the order in which flex items appear within a flex container, regardless of their source order in the HTML. By default, all flex items have an `order` value of 0, but you can assign positive or negative values to rearrange them. `order: ;` Default value is `0`. Items with lower `order` values appear first. Items with equal `order` values are displayed in the order they appear in the HTML. Changing the `order` value only affects visual order, not the document source order. .container { display: flex; border: 1px solid #ccc; } .item { background-color: #3498db; color: white; padding: 20px; margin: 10px; text-align: center; } .item:nth-child(1) { order: 3; } .item:nth-child(2) { order: 1; } .item:nth-child(3) { order: 2; } Item 1 Item 2 Item 3 In this example, although Item 1 appears first in the HTML, it is displayed last because its `order` value is higher than the others. Use `order` sparingly to avoid confusion between visual and source order. Avoid changing order for accessibility-critical elements (e.g., forms, navigation). Prefer logical HTML ordering and use CSS for visual enhancements only.
