Container Animation (Gsap 3.8)

[pattocheu]

Dear All,

 

Hello to all,

I would like to have some explanations about "Container Animation" seen in Gsap 3.8.

 

In my Codepen demo, I can't scroll to the orange DIV and I don't understand what I am doing wrong.

 

Thank you for your help.

Hello there, @pattocheu

 

First up, I would suggest taking a closer look on how flexbox handles things - e.g. if you want your sections to have specific widths, make sure to set the flex properties for them, or else flexbox will kind of do its own thing.

With that corrected, your tween will still not work because you have sections with different widths, so using xPercent with calculations based on the number of sections you have for where to tween things to won't work - those calculations you are using work for sections that all have the same width, filling the screen.

 

As an alternative approach you could tween on the x instead and do your calculations based on the scrollWidth of the container and the clientWidth (or alternatively window.innerWidth).

 

That works better already - Hope it helps

Hi @akapowl

 

Thank you for your reply and the additional information.

 

It is now clearer for me.
