Script.js

Var words = document.querySelectorAll (".word"); words.forEach (function (word) {var letters = word.textContent.split (""); word.textContent = ""; letters.forEach (function (letter) {var span = document.createElement ("span"); span.textContent = letter; span.className = "letter"; word.append (span);}); var currentWordIndex = 0There var maxWordIndex = words.length-1 Words [currentWordIndex] .style.opacity = "1"; var rotateText = function () {var currentWord = words [currentWordIndex]; var nextWord = currentWordIndex = maxWordIndex? Words [0]: words [currentWordIndex + 1]; / / rotate out letters of current word Array.from (currentWord.children) .forEach (function (letter, I) {setTimeout (function () {letter.className = "letter out";}, I * 80);}); / / reveal and rotate in letters of next word nextWord.style.opacity = "1" Array.from (nextWord.children). ForEach (function (letter, I) {letter.className = "letter behind"; setTimeout (function () {letter.className = "letter in";}, 340 + I * 80);}); currentWordIndex = currentWordIndex = = maxWordIndex? 0: currentWordIndex + 1;}; rotateText (); setInterval (rotateText, 4000). Environmental preparation

When the library is missing, there will be a corresponding prompt black window to execute the following command + package name to download and install.
