我已经成功地在JavaScript中制作页面卷曲，但它有点慢， 我可以在纯CSS中翻页吗？
这是代码的一小部分
function drawFlip( flip ) {
// Strength of the fold is strongest in the middle of the book
var strength = 1 - Math.abs( flip.progress );
// Width of the folded paper
var foldWidth = ( PAGE_WIDTH * 0.165 ) * ( 1 - flip.progress/0.5 );
// X position of the folded paper
var foldX = PAGE_WIDTH * flip.progress + foldWidth;
// How far the page should outdent vertically due to perspective
var verticalOutdent = 20 * strength;
// The maximum width of the left and right side shadows
var paperShadowWidth = ( PAGE_WIDTH * 0.5 ) * Math.max( Math.min( 1 - flip.progress, 0.5 ), 0 );
var rightShadowWidth = ( PAGE_WIDTH * 0.5 ) * Math.max( Math.min( strength, 0.5 ), 0 );
var leftShadowWidth = ( PAGE_WIDTH * 0.5 ) * Math.max( Math.min( strength, 0.5 ), 0 );
