+| **backgroundColor**    | string                | `'#1775d1'` (blue) | Background color of the back to top button (hex string).                                                                                           |
+| **bottomOffset**       | string \| number      | `'0px'`            | Offset `px` from bottom of page when scrolled to bottom. For example this can be used to make sure the back to top button never overlaps a footer. |
+| **displayAtYPosition** | string \| number      | `'420px'`          | The back to top button will not be displayed until the user scrolls to the provided Y (vertical `px`) coordinate on the page.                      |
+| **position**           | `'left'` \| `'right'` | `'right'`          | Position on-screen where the back to top button is displayed.                                                                                      |
+| **styleHeight**        | string                | `'25px'`           | Height of back to top button in string px format.                                                                                                  |
+| **styleWidth**         | string                | `'25px'`           | Width of back to top button in string px format.                                                                                                   |
+| **styleZIndex**        | number                | `999`              | Style the `z-index` for the back to top button as needed for correct layer height adjustment. This can be useful when working with sticky headers. |
+
