Pull to Refresh Splittext in IOS Safari.

Go to solution Solved by BenjaminO,

Recommended Posts

Hello folks 👋,


I noticed a strange behavior in Safari IOS 15. When I am pulling the page to refresh it, Splittext isn't refreshed and my animation isn't work. However, when I click on the refreshing button, it does work. I also tried in Firefox on IOS and the 'Pull to refresh' is working as expected. I record an example of this 'bug'. link to the website : https://www.benjaminoddou-photographe.com/about

Am I the only one to have this bug in Safari ? Do you think it that it comes from Splittext itself ?


Thank you in advance for your answers 😉

I don't understand what you mean. I don't see the issue.

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 CodeSandbox that demonstrates the issue? 


Please don't include your whole project. Just some colored <div> elements and the GSAP code is best (avoid frameworks if possible). 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

See the Pen aYYOdN by GreenSock (@GreenSock) on CodePen


If you're using something like React/Next/Nuxt/Gatsby or some other framework, you may find CodeSandbox easier to use. 


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

Hello @GreenSock and thank you very much for your response. The problem can be seen in the video when I first refresh the site, the lines aren't appearing one by one. After digging about this, I think I found the reason of the issue and I wanted to share it. I declared in my code :

window.onresize = function () {

I found out that the problem is caused by the address hiding or showing in mobile browsers, causing the height of the screen to change, hence triggering the onresize function. When I inspect the code in Safari IOS when I pull to refresh the site, the revert function is called instantly meaning (in my opinion) that it triggers the onresize event. 


I wrote a small workaround that works :

let cacheWidth = window.innerWidth;
window.onresize = function () {
  let newWidth = window.innerWidth;
  if(newWidth != cacheWidth) {

Thank you again !
