如何使用 bootstrap 3 为该行的特定列获取行的完整宽度 class

Question

我使用 bootstrap 3 行和列 class 来分隔按钮。第二个按钮是可折叠的，显示 google 地图。但我希望可折叠地图占据该行的整个区域，尽管它位于该行的一列中。可能吗？下面是我的代码：

<div class="row text-center c-green">
   <div class="col-md-6">
     <button class="btn-large btn-form" data-toggle= "modal" data-target=    "#contact-modal">Contact with us</button>
   </div>
    <div class="col-md-6">
      <a href="#map" data-toggle= "collapse" ><button class="btn-large btn-map">Click the button to see our batch location</button></a>
    <div id="map" class= "collapse"></div>
  </div>
</div>

Here is the output image

Answer 1

您必须在 col-md-6 之外包裹地图。

试试这个。

.map-wrapper {
  width: 100%;
}

<link href="https://stackpath.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css" rel="stylesheet"/>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script>
<div class="row text-center c-green">
      <div class="col-xs-6 col-md-6">
        <button class="btn btn-large btn-form" data-toggle= "modal" data-target="#contact-modal">Contact with us</button>
       </div>
       <div class="col-xs-6 col-md-6">
         <a href="#map" data-toggle= "collapse" ><button class="btn btn-large btn-map">Click the button to see our batch location</button></a>
        </div>
        <div id="map" class= "collapse map-wrapper">
