Callback function in a timeline fires before complete

[zimbeta]

Hi Greensock gurus. Been struggling with timing this animation properly. It's business data interactive and I'd like the HTML to be updated from a content object but only at certain intervals. Please see my pen.  

 

Press button "Step 2" or "Step 3."  I want the content of the HTML to update to step 2 description but not until the timeline animation has finished. Why is this onComplete function callback not waiting until the element has stopped moving to change? The idea is the animation will move off the screen or text fade out, then update, then I bring it back in. 

 

Any help or just a general idea? Thanks so much

It looks like the problem is that you've got CSS transitions applied. So every time GSAP changes a property, CSS transitions say "wait! don't do that yet...I'll take 2 seconds and animate those in". So GSAP was doing exactly what you told it to do, and the onComplete was firing appropriately...but your CSS transitions were taking another 2 seconds after that. 

 

See what I mean? 

 

I'd strongly recommend avoiding CSS transitions/animations if you're going to use GSAP to animate things.

This is what happens when you tell CSS and JavaScript to animate the same thing.

Many thanks Jack! I had some leftovers from a previous animation attempt and it was interfering. Now that's I've removed them it seems to work properly.
