<wa-comparison> Stable Since 2.0

Comparisons show the visual differences between two pieces of similar content using a draggable divider. Use them for before/after images, design revisions, or side-by-side previews.

This is especially useful for comparing images, but can be used for comparing any type of content (for an example of using it to compare entire UIs, check out our theme page). For best results, use content that shares 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.)
