如何在較大的屏幕上獲得1個引導程序列以在較小的屏幕上打破2並在移動設備上堆積？

Question

下面是HTML：

<div class="container-fluid"> 
<div class="row fluid"> 
    <div class="nav clearfix"> 
     <div class="col-xs-12 col-sm-6 col-md-4 col-lg-2 col-xl-2 clearfix"> 
      <div class="hotel"> 
       <div class="hotel_img"></div> 
       <h1>Accomodation</h1> 
       <div class="bottom_border"></div> 
       <p> 
        Perfect solution: 
        <span>hotel, apartment, hostel, guest house</span> 
       </p> 
      </div> 
     </div> 
     <div class="col-xs-12 col-sm-6 col-md-4 col-lg-2 col-xl-2 clearfix"> 
      <div class="tour"> 
       <div class="tour_img"></div> 
       <h1>Tourist Attractions</h1> 
       <div class="bottom_border"></div> 
       <p>

        You are hungry:

       </p> 
      </div> 
     </div> 
     <div class="col-xs-12 col-sm-6 col-md-4 col-lg-2 col-xl-2 clearfix">

       <div class="bottom_border"></div>

        It's time to have fun: 
        <span>concerts, cinema, exhibitions</span> 
       </p> 
      </div> 
     </div> 
     <div class="col-xs-12 col-sm-6 col-md-4 col-lg-2 col-xl-2 clearfix"> 
      <div class="coffee"> 
       <div class="coffee_img"></div> 
       <h1>Coffee Shop</h1> 
       <div class="bottom_border"></div> 
       <p> 
        You must wake up: 
        <span>Starbucks, Filicori, Nescafe, Lavazza</span> 
       </p> 
      </div> 
     </div> 
     <div class="col-xs-12 col-sm-6 col-md-4 col-lg-2 col-xl-2 clearfix"> 
      <div class="gov"> 
       <div class="gov_img"></div> 
       <h1>Government</h1> 
       <div class="bottom_border"></div> 
       <p> 
        Must see: 
        <span>parliament building, district court, royal house</span> 
       </p> 
      </div> 
     </div> 
    </div> 
</div> 

它不會打破，取而代之的則只是停留爲1列，並強制滾動條。 我希望它看起來像和堆疊在手機上。而是保持1 2 3 4 5 6在任何屏幕尺寸。代碼對我來說很合適，我不確定是否有什麼東西阻止了它的發展，或者我只是做錯了。有任何想法嗎？

Answer 1

1. 確保您導入的Bootstrap庫。如果沒有它，你的代碼將不會做任何事情。

2. 對於小屏幕，使用col-12來獲得全寬，對於大屏幕，使用col-6來獲得半寬（並排列）。
