3D book turning Effect Based on javascript html5, html5 book turning

This is a cool HTML5 3D book flip animation with relatively simple effects. You can drag and drop the mouse to simulate page flip by hand. What's more beautiful is that the page flip process shows a realistic 3D 3D effect. Text and images in books are displayed in 3D, which is very cool.

JavaScript code

(function (window, document) { var prefixes = ['Webkit', 'Moz', 'ms', 'O', ''], book = document.querySelectorAll('.book')[0], page = document.querySelectorAll('.front-cover')[0], dino = document.querySelectorAll('.dino')[0], shadow = document.querySelectorAll('.shadow')[0], hold = false, centerPoint = window.innerWidth / 2, pageSize = 300, clamp = function (val, min, max) { return Math.max(min, Math.min(val, max)); }; page.onmousedown = function () { hold = true; }; window.onmouseup = function () { if (hold) { hold = false; } }; window.onresize = function () { centerPoint = window.innerWidth / 2; }; window.onmousemove = function (evt) { if (!hold) { return; } var angle = clamp((centerPoint - evt.pageX + pageSize) / pageSize * -90, -180, 0), i, j; for (i = 0, j = prefixes.length; i < j; i++) { book.style[prefixes[i] + 'Transform'] = 'rotateX(' + (60 + angle / 8) + 'deg)'; page.style[prefixes[i] + 'Transform'] = 'rotateY(' + angle + 'deg)'; dino.style[prefixes[i] + 'Transform'] = 'rotateX(' + (angle / 2) + 'deg)'; shadow.style[prefixes[i] + 'Transform'] = 'translateZ(1px) skewX(' + (angle / 8) + 'deg)'; } };})(window, document);

The above is the example code of HTML5 3D book flip animation. I hope it will help you learn javascript programming.
