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">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。
