Pure Javascript implementation of Windows 8 Metro style implementation

Main features of Metro style design

1.Windows 8 Metro style design, realize navigation of website or system functions

2. Pure Javascript implementation

3. Support all common browsers such as IE, 360 and Chrome

4. Support rounded corners, shadows, card switching and other special effects

5. Support card zoom, zoom, add, delete and other functions

Card display part of the code:

 
str='<li data-mode="flip" id="'+itemID+'" data-sizex="1" data-sizey="1" class="stylediv2" style="float:left;left:'+left+'px;top:'+top+'px;width: '+addwidth+'px; height: '+addheight+'px;background-color:'+backColor+';position:absolute;z-index:2; cursor:pointer;border-radius:5px;box-shadow:0 4px 10px rgba(0, 0, 0, .35); behavior: url('+imgBasePath+'js/ie.htc);" onMouseOver="showOption(this)" onMouseOut="hiddeOption(this)">'; 
str+='<div style="float:left;position:absolute;left:0px;top:0px;width: '+addwidth+'px; height: '+addheight+'px;background-color:orange;"></div>'; 
str+='<div style="float:left;position:absolute;left:0px;top:0px;width: '+addwidth+'px; height: '+addheight+'px;background-color:red;"></div>'; 
str+='</li>';
