Bootstrap鏈接在小屏幕上變得無法點擊

Question

我使用引導來設計響應式網站。瀏覽器窗口最大化時鏈接正常工作。但是當我在移動窗口上測試時，鏈接變得無法點擊。

<div class="container-fluid"> 
    <div class="row" style="text-align:center"> 

     <div class="col-lg-9 pull-right col-md-9 col-sm-9 col-xs-4 pull-right" style="height:150px"> 
     <span id="lines" onclick="openNav()"> </span> 
     </div> 

     <div class="col-lg-3 col-md-3 col-sm-3 col-xs-8 content_side"> 
     <div class="col-lg-10 col-md-10 col-sm-10"> 
     <img src="images/logo.png" class="img-responsive" id="img_logo" alt="logo"/> 
     </div> 

     <div class="col-lg-10 col-md-4 col-sm-4"> 
     <ul> 
      <li><a href="pages/a.html"> about </a></li> 
      <li><a href="pages/b.html"> contact </a></li>    
     </ul> 
     </div> 
    </div> 
    </div> 
</div> 



<div class="col-lg-8 col-md-8 col-sm-8 col-xs-8"> 
     <img src="images/home.jpg" class="img-responsive" alt="" id="img1"/> 
     </div> 
     <div class="col-sm-8"> 
     <img src="images/home_img1.jpg" class="img-responsive" alt="" id="img_home1"/> 
     </div> 
     <div class="col-sm-8"> 
     <img src="images/home_img2.jpg" class="img-responsive" alt="" id="img_home2"/> 
     </div> 
     <div class="col-sm-8"> 
     <img src="images/home_img3.jpg" class="img-responsive" alt="" id="img_home3"/> 
     </div> 

     <div class="col-lg-8 col-md-8 col-sm-8 col-xs-11"> 
     <h1 class="home_txt"> Opportunities for start-ups' </h1> 
</div> 

Answer 1

檢查是否有其他元素與鏈接重疊。元素可能在那裏，但不可見。
