The example in this article describes the simple implementation of web page skinning effect using js+css. Share it with everyone for your reference, the details are as follows:

Three sets of appearances are made here, using css files with the same name in different folders. So how to implement js replacement loading?

The 3 buttons are as follows:

<a id="skin1" href="javascript:void(0)" class="easyui-linkbutton" onclick="changeCss('default')">蓝色皮肤</a><br/><br/>
<a id="skin2" href="javascript:void(0)" class="easyui-linkbutton" onclick="changeCss('gray')">灰色皮肤</a><br/><br/>
<a id="skin3" href="javascript:void(0)" class="easyui-linkbutton" onclick="changeCss('unite')">自定义皮肤</a>

js code:

// 更换主题
function changeCss(cssName) {
  if (document.getElementsByTagName_r("link").length > 0) {
   for(var i = 0 ; i < document.getElementsByTagName_r("link").length; i++){
    var ctrlLink = document.getElementsByTagName_r("link")[i];
    var cssOld = ctrlLink.getAttribute("href");
    var cssNew = cssOld.replace("default", cssName);
    cssNew = cssNew.replace("gray", cssName);
    cssNew = cssNew.replace("unite", cssName);
    ctrlLink.setAttribute("href", cssNew);
   }
  }
}

Realization effect:
