1、新建html文档。

2、书写hmtl代码。
<div class="wrapper">
<h1>效果演示</h1>
<div class="list">
<div class="item selected">
<div class="text">
<h2> 数字跑动场景</h2>
<div class="attr">
<dl>
<dd class="d1">
<h4>目标额</h4>
<h3><span class="animateNum" data-animatetype="num" data-animatetarget="999.9">999.9</span>万</h3>
</dd>
<dd class="d2">
<h4>已完成</h4>
<h3><span class="animateNum" data-animatetarget="30">30</span>%</h3>
</dd>
<dd class="d3">
<h4>已认投</h4>
<h3><span class="animateNum" data-animatetarget="999.9">999.9</span>万</h3>
</dd>
</dl>
</div>
</div>
</div>
<div class="item selected">
<div class="text">
<h2> 柱形图跑动场景 </h2>
<h3>目标额</h3>
<div class="prograss">
<div class="bar animateBar" data-animatetarget="30" style="width:30%;"></div>

</div>
</div>
</div>
<div class="item">
<div class="text">
<h2> 圆圈统计图跑动场景 </h2>
<h3>目标额</h3>
<div class="pie animatePie" data-animatetarget="65">
<div class="pieLeft">
<div class="pieLeftInner"></div>
</div>
<div class="pieRight">
<div class="pieRightInner"></div>
</div>
<div class="pieInner"><span>65</span>%</div>
</div>
<h3>已完成</h3>
<div class="pie animatePie" data-animatetarget="65">
<div class="pieLeft">
<div class="pieLeftInner"></div>
</div>
<div class="pieRight">
<div class="pieRightInner"></div>
</div>
<div class="pieInner"><span>65</span>%</div>
</div>
<h3>已认投</h3>
<div class="pie animatePie" data-animatetarget="65">
<div class="pieLeft">
<div class="pieLeftInner"></div>

</div>
<div class="pieInner"><span>65</span>%</div>
</div>
</div>
</div>
</div>
</section>
</div>

3、书写css代码。
html { -webkit-text-size-adjust: none; }
body { color: #000000; font-family: Verdana, Arial, Helvetica, sans-serif; }
a { outline: none; text-decoration: none; }
a:hover { text-decoration: underline; }
html { zoom: 1; }
html * { outline: 0; zoom: 1; }
html button::-moz-focus-inner {
border-color:transparent!important;
}
body { overflow-x: hidden; font-size: 12px; }
body, div, dl, dt, dd, ul, ol, li, h1, h2, h3, h4, h5, h6, pre, code, form, fieldset, legend, input, textarea, p, blockquote, th, td { margin: 0; padding: 0; }
table { }
fieldset, a img { border: 0; }
address, caption, cite, code, dfn, em, th, var { font-style: normal; font-weight: normal; }
li { list-style: none; }
caption, th { text-align: left; }
h1, h2, h3, h4, h5, h6 { margin-top: 20px; }
q:before, q:after { content: ''; }

.list .item .attr dd h3 { color: #e95549; font-size: 30px; font-weight: bold; }
.list .item .lst { margin-top: 10px; }
.list .item .lst dl { height: auto; overflow: hidden; }
.list .item .lst dd { width: 50%; float: left; display: inline; font-size: 24px; line-height: 40px; }
.list .item .lst dd span { color: #e95549; margin-left: 10px; }
.list .item .tags { margin-top: 15px; }
.list .item .tags span { background: #f8f8f8; height: 32px; line-height: 32px; display: inline-block; padding: 0 20px; margin-right: 15px; }
.pie { width: 120px; height: 120px; border-radius: 50%; background: #e95549; position: relative; margin-top: 20px; }
.pieLeftInner, .pieRightInner { width: 120px; height: 120px; background-color: #e5e5e5; border-radius: 100px; position: absolute; }
.pieLeftInner { clip: rect(0px,120px,120px,60px); -o-transform: rotate(0deg); -moz-transform: rotate(0deg); -webkit-transform: rotate(0deg); }

.prograss_bar_yellow { background: #f8b757 !important; }

4、书写并添加js代码。
<script src="js/jquery.min.js"></script>
<script src="js/jquery.running.min.js"></script>
<script src="js/docs.js"></script>
5、书写docs.js代码。
<script>
$(function(){
$('body').running();
$(window).bind("scroll",function(){
var top=$(window).scrollTop();
$('.list .item').each(function(){
if ($(this).offset().top -top< $(window).height() - 200){
$('.list .item').removeClass('selected');
$(this).addClass('selected');
};
})
});
})
</script>

6、代码整体结构。

7、查看效果。
