Maybe it will be slow on some devices. Can you please provide me with some information about your device and browser? Loading did slow or functionality of it? About coding : Absolutely not. As you can see, it's totally PWA, Vue.js, (because needs fast functionality in countries with low-speed internet.) I realized that it works slowly in Safari because of DOM animation. So I disabled autoplay.
