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

How can get full width of a row class for a specific column of that row using bootstrap 3

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

您必须在 col-md-6 之外包裹地图。

试试这个。

.map-wrapper {
  width: 100%;
}
