JS CSS creates DIV layer that can (minimize/drag/sort) function implementation code_javascript skills

Copy code The code is as follows: JS+CSS制作的DIV层最小化和随意拖拽排序功能 body { margin:10px; } #dragHelper { position:absolute;/*重要*/ border:2px dashed #000000; background-color:#FFFFFF; filter: alpha(opacity=30);
