如何修复我的网站中的错误

Question

所以我经历了一个奇怪的锚元素生成，我无法摆脱它。它看起来好像有一个：before和：after元素随机生成一些但是我不确定是什么。代码似乎很好：

<div class="row">
    <div class="small-12 columns">
       <h1>Social Science</h1>
<!--       Algebra 1 Common Core Semester 1-->

        <dl class="accordion accorborder" data-accordion="">
        <dd class="accordion-navigation">
            <a href="#p1">World History Since Renaissance Sem 1</a>
            <div id="p1" class="content">
               <div class="row">
                   <div class="small-6 columns">
                        <h6>Code:</h6>HS-ES-141
                        <h6>Offerings:</h6><span class="label">OFL</span><span class="label success">OFY</span><span class="label alert">PIE</span>
                   </div>
                   <div class="small-6 columns">

                       <h6>Course Materials:</h6> 
                       <ul>

                           </li>
                       </ul>
                   </div>
               </div> 
                <p>txt

                </p>
<!--                Panels-->
        <dl class="tabs" data-tab>
        <dd class="active"><a href="#p1a">Study Sheets</a></dd>
        <dd><a href="#p1b">Study Sheets Answer Keys</a></dd>

        <dd><a href="#p1d">Graded Assignment Answer Keys</a></dd>
      </dl>
      <div class="tabs-content">
        <div class="content active" id="p1a">
              <ul class="ss">
              <li><a 
              </ul>
        </div>
      </div>       
            </div>  
        </dd>
        </dl>

<!--        wh2-->

        <dl class="accordion accorborder" data-accordion="">
        <dd class="accordion-navigation">
            <a href="#p2">World History Since Renaissance Sem 2</a>
            <div id="p2" class="content">

                        <h6>Offerings:</h6><span class="label">OFL</span><span class="label success">OFY</span><span class="label alert">PIE</span>

                   </div>
                   <div class="small-6 columns">

我删除了一些代码但是它的要点。如需仔细观察，请检查http://new.omegadesignla.com/courses/socialScience.php上的元素，看看前2支手风琴上出现的额外锚点。感谢。
