I wanted to move the height of a div with tweenlite...

TweenLite.to('div', 10, {bottom: '85%'});

But, it's not work. The value jump to 0 and doesn't take the original value of 80%.

The element is not define with height but with position: absolute.

position: absolute;
  top: 10%;
  bottom: 80%;
  left: 50%;
  right: 40%;

I wanted to signal this and know if it's "normal" or if it's just me.


My Codepen test :


Thank for answer :)

Hi and welcome to the GreenSock forums,


Thanks for the demo.


Not sure I understand the problem. If you look in dev tools and inspect the element you will see the inline styles are updating properly: http://prntscr.com/c0o3ub.


Change the end value with a longer duration to make it more obvious that it works: http://codepen.io/GreenSock/pen/bZxRRZ

This is science-fiction.

When i post the Codepen, it doesn't work, and now it works perfectly.
Maybe due to Chrome's update.

Sorry for the useless topic.
And thanks for the quick answer.

Thanks for letting us know. I think every JS developer has lost many hours to mysterious happenings;)
