How to use GSAP on mobile devices?

[Aterlab]

Hello, so I started making this website: https://puimawar.netlify.app and everything works on desktop (I used GSAP in every section), but when I test it on mobile, the text doesn't appear and the draggables in 4th section also don't appear.

Without a minimal demo, it's very difficult to troubleshoot; the issue could be caused by CSS, markup, a third party library, a 3rd party script, etc. Would you please provide a very simple CodePen or Stackblitz that illustrates 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 dependencies as possible. Start minimal and then incrementally add code bit by bit until it breaks. Usually people solve their own issues during this process! If not, at least we have a reduced test case which greatly increases your chances of getting a relevant answer.

 

See the Pen aYYOdN by GreenSock (@GreenSock) on 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 GSAP as shown in the Install Helper in our Learning Center : 

• 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. ✅

Hi @Aterlab and welcome to the GSAP Forums!

 

There is not much we can do to debug a live site so unfortunately I can't really tell you what could be the issue.

 

I'd recommend you to have a look at GSAP MatchMedia
https://gsap.com/docs/v3/GSAP/gsap.matchMedia()

 

But doing a quick test on the browser with devtools to emulate a device I noticed that you have a lot of horizontal scrolling available, so my advice would be to try this on mobile screen sizes first without any GSAP in it and see if the HTML and CSS work the way they should first. Keep in mind that when developing normally you try the HTML and CSS for small screens first you should do the same with GSAP, test your animations on mobile first and then scale up to desktop. Also some developers like to simplify animations to the bare minimum on devices in order to save battery, so normally they not only simplify the designs but also the development for small screens.

 

Finally if possible try to include a minimal demo (emphasis on minimal) that clearly shows the issue you're having.
