CSS3實現的滑鼠懸浮開門關門效果代碼執行個體:
本章節分享一段代碼執行個體，它利用CSS3類比實現了簡單的開門關門效果。
代碼執行個體如下:
<!DOCTYPE html><html> <head> <meta charset=" utf-8"> <meta name="author" content="http://www.softwhy.com/" /> <title>螞蟻部落</title><style>.door{ position:relative; width:400px; height:300px; overflow:hidden; border:2px solid #000; background:#000;}.door:before,.door:after{ content:''; position:absolute; left:0; width:0; height:0; overflow:hidden; border-color:#000 transparent transparent transparent; border-style:solid; border-width:0 200px; z-index:2; transition:all .8s ease;}.door:before{top:0;}.door:after{ bottom:0; border-color:transparent transparent #000 transparent;}.door:hover:before,.door:hover:after{border-width:40px 200px;}.door-left, .door-right{ position:relative; float:left; width:50%; height:100%; background:#f00; box-sizing:border-box; transition:all .5s ease;}.door-left{ border-right:2px solid #000; -webkit-transform-origin:0 0; } .door-left:before,.door-right:before{ content:''; position:absolute; width:10px; height:10px; top:50%; margin-top:-5px; border-radius:50%; background:#000; } .door-left:before{right:5px;} .door-right:before{left:5px;} .door-right{ border-left:2px solid #000; -webkit-transform-origin:100% 0; } .door:hover .door-left{ -webkit-transform:rotateY(-90deg); transition:all .8s ease-out; } .door:hover .door-right{ -webkit-transform:rotateY(90deg); transition:all .8s ease-out; }</style></head><body><div class="door"> <div class="door-left"></div> <div class="door-right"></div></div></body></html>
上面的代碼實現了我們的要求，代碼根本無需過多介紹，只需要明白各個屬性的原理就可以了。
