For best results, use images that share the same dimensions. The slider can be controlled by dragging or pressing the left and right arrow keys. (Tip: press shift + arrows to move the slider in larger intervals, or home + end to jump to the beginning or end.)

## Examples

### Initial Position

Use the `position` attribute to set the initial position of the slider. This is a percentage from `0` to `100`.

```html {.example}
<wa-image-comparer position="25">
