    <div class="F-SlideFont-Box">

            <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。
