Scrollmagic duration

问题

Is there a way to set the scrollmagic duration on a scene as long as the height of the scene? I want to use the class toggles functionality and certain scenes are heigher than the viewport height.

<section id="sec1">I'm 400px in height</section>
<section id="sec1">I'm 100% in height (1 viewport)</section>
<section id="sec1">I'm 2500px in height (2,2 viewports)</section>

Duration in px: {duration: 400}

Duration in vh: {duration: '100%'}

Duration in element height: ???

Thanks for helping!

Try using $("#sec1").height() in the duration option.
