### Introduction

In HarmonyOS Next, child elements use the *.position()* attribute for relative positioning within parent elements. Usage example:

``` @Entry @Component struct PositionExample1 { build() { Column() { Row() {

        }
        .position({x: 50, y: 50})
    }
    .width('100%')
    .height('100%')
  }

} ```

This positions the child element 50 units from the parent's left and top edges.

A common challenge is positioning elements near the right edge, especially given the diverse screen sizes across devices. How can we ensure consistent positioning across different devices?

We propose a solution using the LocalizedEdges type. This approach accounts for device diversity by:

1. Identifying device types 2. Adapting to screen dimensions 3. Maintaining consistent positioning across devices

### Solution

Official documentation: \#position

Use LocalizedEdges for positioning relative to parent container edges, with mirroring support. This is ideal for:

- Fixed-position elements - Floating action buttons - Top-aligned components - Edge-sensitive designs

Example of bottom-right positioning:

``` @Entry @Component struct PositionExample1 { build() { Column() { Row() {

        }
        // bottom: Offset from bottom edge
        // end: Offset from right edge (supports RTL mirroring)
        .position(bottom: { value: 20, unit: 2 }, end: { value: 20, unit: 2 })
    }
    .width('100%')
    .height('100%')
  }

} ```

Key features:

- `unit: 2` specifies percentage-based positioning - Works consistently across all screen sizes - Automatically adjusts for right-to-left languages - Maintains design integrity on any device

This concludes our overview of advanced positioning techniques in HarmonyOS Next.
