        <title> html5 drag and drop</title>
        <style>

            }
            a.move {
                -webkit-transform:scale3d( 1.1, 1.1, 1.1 );
            }
            a:hover:after {

        </style>

    <body>
        <div class="container">

            }).on("dragover",
            function(e) {

每日一句:I always knew looking back on the tears would make me laugh, but I never knew looking back on the laughs would make me cry.

翻译:我知道再回首时,那些眼泪想来可笑;却不知再回眸时,那些欢声笑语也能叫我潸然泪下。
