CSS

復(fù)制代碼代碼如下:

 * {

     margin: 0;

     padding: 0;

 }

 #main {

     position: relative;

 }

 .box {

     padding:15px 0 0 15px;

     float:left;

 }

 .pic {

     padding: 10px;

     border: 1px solid #ccc;

     border-radius: 5px;

     box-shadow: 0px 0px 5px #ccc;

     img {

         width:165px;

         height:auto;

     }

 }

                 var oPic=$("<div>").addClass('pic').appendTo($(oBox));

                 $("<img>").attr("src","images/"+$(value).attr("src")).appendTo(oPic);

             });

             waterfall();
