css – bootstrap 4行高

我试着用bootstrap 4 这样的东西

在绿色行和红色行的高度相同的大小

<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-alpha.6/css/bootstrap.css" rel="stylesheet"/>
   <div class="container">
        <div class="row">
          <div class="col-md-8 col-lg-6 B"><div class="card card-inverse" style="background-color: #333; border-color: #333;">
    <img src="http://lorempicsum.com/rio/800/500/4" class="img-fluid" alt="Responsive image">
    
    </div></div>
      <div class="col-md-4 col-lg-3 G">
          <div class="row">
          <div class="col-md-6 col-lg-6 B"><div class="card card-inverse" style="background-color: #333; border-color: #333;">
    <img src="http://lorempicsum.com/rio/800/500/4" class="img-fluid" alt="Responsive image">
    
    </div></div>
       <div class="col-md-6 col-lg-6 B"><div class="card card-inverse" style="background-color: #333; border-color: #333;">
    <img src="http://lorempicsum.com/rio/800/500/4" class="img-fluid" alt="Responsive image">
    
    </div></div>
       <div class="col-md-12"><div class="card card-inverse" style="background-color: #333; border-color: #333;">
    <img src="http://lorempicsum.com/rio/800/500/3" class="img-fluid" alt="Responsive image">
    
    </div></div>
       </div>
    </div>   
       
        </div>
    </div>

所有图像都具有相同的大小并且响应迅速
但问题是我无法在绿色行和红色行的高度上获得相同的大小

解决方法

使用大小调整实用程序类…

> h-50 =身高50％
> h-100 =身高100％

                <div class="card card-inverse card-primary">
                    <img src="http://lorempicsum.com/rio/800/500/4" class="img-fluid" alt="Responsive image">

                <div class="row h-100">
                    <div class="col-md-6 col-lg-6 B h-50 pb-3">
                        <div class="card card-inverse card-success h-100">

                        </div>
                    </div>
                    <div class="col-md-6 col-lg-6 B h-50 pb-3">
                        <div class="card card-inverse bg-success h-100">

                        </div>
                    </div>
                    <div class="col-md-12 h-50">
                        <div class="card card-inverse bg-danger h-100">

                        </div>
                    </div>
                </div>
            </div>
        </div>
    </div>

或者,对于未知数量的子列,使用flexBox,cols将填充高度.请参阅行上的d-flex flex-column和子列上的h-100.
