This is a very cool HTML5 3D book page animation, the effect is relatively simple, drag and drop the mouse simulation hand-page, more beautiful is the process of turning the page, showing a realistic 3D stereo effect. The text and pictures in the books will also be displayed in 3D, very cool.

JavaScript code

(Function (window, document) {var prefixes = [' Webkit ', ' Moz ', ' Ms ', ' O ', '], book = Document.queryselectorall ('. Boo K ') [0], page = Document.queryselectorall ('. Front-cover ') [0], Dino = Document.queryselectorall ('. Dino ') [0], shadow = doc Ument.queryselectorall ('. Shadow ') [0], hold = false, CenterPoint = WINDOW.INNERWIDTH/2, pageSize =, clamp = funct
 Ion (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 (' + (+ 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 HTML5 3D book page animation of the example code, I hope to learn about JavaScript programming help.
