Bootstrap中移動設備上的另一個菜單內容3

Question

這裏是我用來顯示菜單的代碼。正如你可能看到的那樣，菜單項是圖像而不是文本。當您點擊切換按鈕時，我想要做的是恢復顯示文本鏈接，而不是手機和小屏幕設備的圖像。我沒有任何線索！？

<nav class="navbar navbar-default header-sketch"> 
     <div class="container-fluid"> 
      <!-- Brand and toggle get grouped for better mobile display --> 
      <div class="navbar-header"> 
       <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false"> 
        <span class="sr-only">Toggle navigation</span> 
        <span class="icon-bar"></span> 
        <span class="icon-bar"></span> 
        <span class="icon-bar"></span> 
        <span class="icon-bar"></span> 
        <span class="icon-bar"></span> 
       </button> 
         <a class="navbar-brand" href="index.html#top"><img class="logo" alt="CarShare Logo" src="img/car-logo.png"></a> 
      </div> 

      <!-- Collect the nav links, forms, and other content for toggling --> 
      <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"> 
       <ul class="nav navbar-nav navbar-right desktop"> 
        <li><a class="toscroll" href="#top" title="Home"><img alt="Home" src="img/home.png"></a></li> 
        <li><a class="toscroll" href="#about" title="About CarShare"><img alt="About CarShare" src="img/about.png"></a></li> 
        <li><a class="toscroll" href="#signup" title="Sign Up"><img alt="Sign Up" src="img/signup.png"></a></li>     
       </ul> 
      </div><!-- End Navbar Collapse --> 
     </div><!-- End Container Fluid --> 
    </nav><!-- End Nav --> 

Answer 1

將類hidden-xs添加到圖像，將'visible-xs'添加到文本。 更多你可以在這裏閱讀關於responsive utilities of bootstrap eg。

<a href="#"> 
    <span class="visible-xs">Home</span> 
    <img class="hidden-xs" alt="Home" src="img/home.png"> 
</a>
