很绚丽的效果幺!
二、实现原理
将要高亮显示的文字加上<span>段落标记, class=”mask”的div 做为遮罩层,使此遮罩层位于文字内容之上(z-index属性,使用Jquery给段落动态添加样式类。
三、HTML代码
<div class="wrapper">
<ul class="entity-results">
<li><a class="d1" href="#">Summary</a></li>
<li><a class="d2" href="#">Avatar</a></li>
<li><a class="d3" href="#">Formats</a></li>
</ul>
<div class="content">
