一：先布局出div
<div class="col col-md-4" data-paroller-factor="0.5" data-paroller-type="foreground">
<div class="card">
<img class="card-img-top" src="images/img2.jpg">
<div class="card-block">
<h4 class="card-title">Card vertical</h4>
<p class="card-text">
<code>data-paroller-factor="0.5" data-paroller-type="foreground"</code>
</p>
</div>
</div>
</div>
二：代码实现
<script src="js/jquery.js"></script>
<script src="js/jquery.paroller.js"></script>
<script>
$(function () {
$(window).paroller();
});
</script>
