jo85 Posted February 15 Share Posted February 15 hello dear gsap community, i'm relatively new to coding, so i guess this is a simple question for some of you: i have animated the background image of the header of my website with gsap fromto. i now want the animatiuon to differ desktop and mobile and would like to use matchMedia for this. This is my code: $(".c-hero.cc-home").each(function (index); let mm = gsap.matchMedia(); mm.add("(min-width: 800px)", () => { // desktop setup code here... gsap .timeline({ scrollTrigger: { trigger: $(this), scrub: true }, defaults: { ease: "none" } }) .fromTo($(this).find(".c-hero-home_bg"), { backgroundPosition: "50% 150%" }, { backgroundPosition: "50% -75%" }) .fromTo($(this).find(".c-hero-content"), { yPercent: 0 }, { yPercent: -20 }, 0); }); mm.add("(max-width: 799px)", () => { { // mobile setup code here... }); I think I have an error somewhere regarding the bracket substitution. can anyone help? thanks and best johannes Link to comment Share on other sites More sharing options...
GSAP Helper Posted February 15 Share Posted February 15 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 dependancies 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 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. ✅ Link to comment Share on other sites More sharing options...
Solution Rodrigo Posted February 15 Solution Share Posted February 15 Hi, You have two opening curly brackets in your add method: // Wrong mm.add("(max-width: 799px)", () => { { // RIGHT HERE AN EXTRA CURLY BRACKET // mobile setup code here... }); // Right mm.add("(max-width: 799px)", () => { // ONE OPENING CURLY BRACKET // mobile setup code here... }); Hopefully this helps. Happy Tweening! Link to comment Share on other sites More sharing options...
