Defaults to #000) | | backgroundScrollSpeed | number | No | The speed factor that the background moves at relative to the foreground. Defaults to 5. | | contentBackgroundColor | string | No | This is the background color of the content. (Defaults to '#fff') | | fadeOutForeground | bool | No | If true, the foreground will fade out as the user scrolls up. (Defaults to true) | | onChangeHeaderVisibility | func | No | A callback function that is invoked when the parallax header is hidden or shown (as the user is scrolling). Function is called with a boolean value to indicate whether header is visible or not. | | parallaxHeaderHeight | number | Yes |This is the height of parallax header. | | renderBackground | func | No | This renders the background of the parallax header.
