An `Element` represents a component on the editor's canvas, allowing you to interact with its attributes and behavior. The [`getSelection()`](https://dev.wix.com/docs/sdk/host-modules/editor/elements/get-selection.md) method returns one or more `Element` objects, and the [`onSelectionChange()`](https://dev.wix.com/docs/sdk/host-modules/editor/elements/on-selection-change.md) event handler receives them as arguments when the selection changes.
