translate3d doesn't work properly in Firefox

[Spider Web Design]

I have popup dialogs that are setup to absolute center on the screen with translate3d(-50%, -50%) and they don't work with GSAP on Firefox mobile.  I think it's an issue with Firefox.  It shows translate(0) for some reason.  You can see it in action @ www.mylottomoney.com

It's pretty tough to troubleshoot without a minimal demo - the issue could be caused by CSS, markup, a third party library, your browser, an external script that's totally unrelated to GSAP, etc. Would you please provide a very simple CodePen or Stackblitz that demonstrates the issue? 

 

Please don't include your whole project. Just some colored <div> elements and the GSAP code is best. See if you can recreate the issue with as few dependancies as possible. If not, incrementally add code bit by bit until it breaks. Usually people solve their own issues during this process! If not, then at least we have a reduced test case which greatly increases your chances of getting a relevant answer.

 

Here's a starter CodePen that loads all the plugins. Just click "fork" at the bottom right and make your minimal demo:

Using a framework/library like React, Vue, Next, etc.? 

CodePen isn't always ideal for these tools, so here are some Stackblitz starter templates that you can fork and import the gsap-trial NPM package for using any of the bonus plugins: 

• React (please read this article!)
• Next
• Svelte
• Sveltekit
• Vue
• Nuxt

 

Please share the StackBlitz link directly to the file in question (where you've put the GSAP code) so we don't need to hunt through all the files. 

 

Once we see an isolated demo, we'll do our best to jump in and help with your GSAP-specific questions.

Also make sure that you're setting all the transforms directly through GSAP rather than CSS because CSS doesn't handle transform-origin consistently across browsers (but GSAP does). 

 

Once we see a minimal demo that clearly illustrates the issue, I'm sure we'll be able to offer some advice.

Thanks for the Pen idea.  I found the problem.  I removed 'bounds: container' and now everything works fine.  The problem was only occurring in Firefox mobile. 

 

The dialog window was offset from the center.  It had the LEFT side of the dialog in the center of the screen instead of the center of the dialog in the center of the screen.  Just removed the bounds and it's mint now.

 

    Draggable.create(dialogWrapper, { bounds: '.container', trigger: handle, transformOrigin: "50% 50%" });
