我尝试用bootstrap 4来做这样的事情

<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和响应,但问题是我不能在绿色行和红色行的高度获得相同的大小

使用大小调整实用程序类...

• h-50 =身高50%
• h-100 =身高100%

 <div class="container">
        <div class="row">
            <div class="col-md-8 col-lg-6 B">
                <div class="card card-inverse card-primary">
                    <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 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.见d-flex flex-column的row,并且h-100对孩子的cols.

<div class="container">
    <div class="row">
        <div class="col-md-8 col-lg-6 B">
            <div class="card card-inverse card-primary">
                <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 d-flex flex-column h-100">
                <div class="col-md-6 col-lg-6 B h-100">
                    <div class="card bg-success h-100">

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

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

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