Hello, i'm Viewport and i'm painted red.
You can resize me vertically, and i'll still track my little childrens correctly ^_^
Below you can see my JS code.


$( '.scrollable-wrapper' ).find( '.element' ).viewportTrack( function ( state ) {
	if ( state.inside ) {
		$( this ).find( 'span' ).text( 'I am inside the viewport ^_^' );
		ghost.find( '.element.' + $( this ).attr( 'el_num' ) + ' span' ).text( 'I am inside the viewport ^_^' );
	} else {
		$( this ).find( 'span' ).text( 'I am outside the viewport T_T' );
		ghost.find( '.element.' + $( this ).attr( 'el_num' ) + ' span' ).text( 'I am outside the viewport T_T' );
	}
} );
