HTML：

<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>SlideFont</title></head><body> <div class="F-SlideFont-Box">  <dl class="F-SlideFont-Box-Tag">   <dd class="F-SlideFont-Tag">谷歌</dd>   <dd class="F-SlideFont-Tag">百度</dd>   <dd class="F-SlideFont-Tag">阿里</dd>   <dd class="F-SlideFont-Tag">苹果</dd>   <dd class="F-SlideFont-Tag">三星</dd>   <dd class="F-SlideFont-Tag">耳机</dd>   <dd class="F-SlideFont-Tag">音箱</dd>   <dd class="F-SlideFont-Tag">电视</dd>   <dd class="F-SlideFont-Tag">谷歌</dd>   <dd class="F-SlideFont-Tag">百度</dd>   <dd class="F-SlideFont-Tag">阿里</dd>  </dl> </div></body></html>

css:

 <style>  .F-SlideFont-Box * { margin: 0; padding: 0; border: none; list-style: none; }  .F-SlideFont-Box { width: 300px; height: 300px; border: 1px black solid; position: relative; }  .F-SlideFont-Box-Tag { width: 90%; height: 90%; position: absolute; top: 0; right: 0; bottom: 0; left: 0; margin: auto; }  .F-SlideFont-Tag { position: absolute; display: block; padding: 3px 15px; background-color: #0078F7; border-radius: 10%; color: white; transition:all 1s linear; z-index: 0; transition: all .6s; cursor: pointer; } </style>

JS:

<script src="js/GlunefishLibrary.js"></script>  // 这里引入的是我发过的随随机数<script> var tagObj = document.getElementsByClassName('F-SlideFont-Tag'),  offset = true; for(var i=0;i<tagObj.length;i++){  (function(i){   tagObj[i].onmouseover = function(){   offset = false;   index = parseInt(this.style.zIndex);   this.style.zIndex = 9999;   }   tagObj[i].onmouseout = function(){   offset = true;   this.style.zIndex = index;   }  })(i); } setInterval(PreSeting,5000) function PreSeting(){  if(offset){   for(var i=0;i<tagObj.length;i++){    tagObj[i].style.left = F_getSJS(200,20,10) + 'px';   //F_getSJS() 来自前面引入的 glunefishLibrary.js ， 具体请移步到我之前的取随机数随笔    tagObj[i].style.top = F_getSJS(200,20,10) + 'px';    tagObj[i].style.backgroundColor = 'rgb(' + F_getSJS(256,-1,5) + ',' + F_getSJS(256,-1,10) + ',' +  F_getSJS(256,-1,15) + ')';    tagObj[i].style.zIndex = F_getSJS(200,0,16);   }  } }</script>

此效果主要通过间隔取两数之间的随机数来改变标签的样式。
