I'm a newbie trying to use React Spring in my React (16.8) project. I made a little carousel which works, but I want to add a credit at the bottom of each slide which should stagger in. A credit consist of two items and the second should animate in a tad slower than the first.



For this I want to use Trail but while the contents of the Trail renders, the animation does not fire.



This is my code so far:






const slides = [

id: 0,
desktopImage: "http://lorempixel.com/400/200/",
title: "foo",
studio: "bar"
,

id: 1,
desktopImage: "http://lorempixel.com/400/200/",
title: "foo",
studio: "bar"
,

id: 2,
desktopImage: "http://lorempixel.com/400/200/",
title: "foo",
studio: "bar"

];

const [slideIndex, set] = useState(0);
useEffect(
() =>
void setInterval(() => set(state => (state + 1) % slides.length), 4000),
[]
);

const transitions = useTransition(slides[slideIndex], item => item.id,
from: opacity: 0, left: -10 ,
enter: opacity: 1, left: -100 ,
leave: opacity: 1, left: -100 ,
config: friction: 25, duration: 4000
);

return (
<div className="header">
transitions.map(( item, props, key ) =>
let bgImg = item.desktopImage;
const creditArray = [item.title, item.studio];

return (
<div key=key>
<animated.div
className="bg"
style= ...props, backgroundImage: `url($bgImg)`
/>
<div className="imageCredit">

<Trail
key=key
items=creditArray
keys=key
from= opacity: 0, transform: "translate3d(-100, 0, 0)"
to= opacity: 1, transform: "translate3d(0, 0, 0)"
>
item => props => <div className="h4">item</div>
</Trail>

</div>
</div>
);
)
</div>
);

          Figured it out, I forgot to pass downn the actual style down to the rendered element.



          so instead of :



          <Trail

          items=creditArray
          keys=key

          item => props => <div className="h4">item</div>
          </Trail>


          I needed to do:



          <Trail
          items=creditArray
          keys=item => item + key
          from=opacity: 0, transform: 'translateX(100px)'
          to=opacity: 1, transform: 'translateX(0)'>
          item => style => (

              </Trail>


              I needed to do:



              <Trail
              items=creditArray
              keys=item => item + key
              from=opacity: 0, transform: 'translateX(100px)'
              to=opacity: 1, transform: 'translateX(0)'>
              item => style => (
              <animated.div style= ...style className="h4">
              item
              </animated.div>
              )
              </Trail>

                Figured it out, I forgot to pass downn the actual style down to the rendered element.



                so instead of :



                <Trail
                key=key
                items=creditArray
                keys=key
                from= opacity: 0, transform: "translate3d(-100, 0, 0)"
                to= opacity: 1, transform: "translate3d(0, 0, 0)" >
                item => props => <div className="h4">item</div>
                </Trail>
