在课程《CSS3+JS 实现超炫的散列画廊特效》第二章——2-3 3D效果编写中,照着老师的讲解敲的和视频一样的代码,为什么没有出现老师说的反转字体的效果?      <!DOCTYPE html> <html lang="en"> <head>     <meta charset="UTF-8">     <script ></script>     <title></title>     <style>         * {             margin: 0;             padding: 0;         }         body {             background-color: white;             color: #555;             font-family: 'KaiTi';             font-size: 16px;             -webkit-font-smoothing: antialiased;         }         .wrap {             width: 100%;             height: 600px;             position: absolute;             top: 50%;             margin-top: -300px;             background-color: #CECBCE;             overflow: hidden;             -webkit-perspective: 800px;         }         .photo {             width: 260px;             height: 320px;             position: absolute;             z-index: 1;             box-shadow: 0 0 1px rgba(0, 0, 0, .01);         }         .photo .side {             width: 100%;             height: 100%;             background-color: #9bdddc;             position: absolute;             top: 0;             right: 0;             padding: 20px;             box-sizing: border-box;         }         .photo .side-front {         }         .photo .side-front .image {             width: 100%;             height: 250px;             line-height: 250px;             overflow: hidden;         }         .photo .side-front .image img {             width: 100%;         }         .photo .side-front caption {             text-align: center;             font-size: 16px;             line-height: 50px;         }         .photo .side-back {         }         .photo .side-back .desc {             color: #562fff;             font-size: 16px;             line-height: 1.5em;         }         .photo_center {             left: 50%;             top: 50%;             margin: -160px 0 0 -130px;             z-index: 999;         }         .photo-wrap{             position: absolute;             width: 100%;             height: 100%;             -webkit-transform-style: preserve-3d;         }         .photo-wrap .side-front{             -webkit-transform: rotateY(0deg);         }         .photo-wrap .side-back{              -webkit-transform: rotateY(180deg);          }     </style> </head> <body onselectstart="return false"> <div class="wrap">     <div class="photo photo_center">         <div class="photo-wrap">             <div class="side side-front">                 <p class="image"><img src="image/1.jpg"/></p>                 <p class="caption">这是一座房子</p>             </div>             <div class="side side-back">                 <p class="desc">描述信息</p>             </div>         </div>     </div> </div> </body> </html>按照视频的说法,此时应该显示的是反转的背面字体,但我的还是正面的图片,是有什么细节遗漏了吗??
