Bootstrap-Raster-Layout Problem - nicht wie

Question

All meine Artikel in dem Grid-Layout bestimmt sind, auf die gleiche Höhe eingestellt, aber ich habe immer noch das Problem:

<!-- featured-box --> 
<div class="featured-box"> 

    <div class="col-md-4 col-sm-4 col-xs-6"> 
     <div class="video-box featured-event-box">

        </div> 
       </div> 

       <div class="col-md-8">

    padding: 0 0 15px 0; 
    border-bottom: 1px solid #b2b2b2;

*/ 
.featured-event-box { 
    padding: 15px; 
    margin: 15px 0 15px 0; 
    min-height: 196px; 
    overflow: hidden;

    box-shadow:   inset 0 0 10px #e6e6e6; 
} 

.featured-event-image-box { 
    margin-bottom: 15px; 
} 

.featured-event-heading a { 
    font-size: 14px; 
    color: inherit; 
} 

.featured-event-heading a:hover { 
    text-decoration: none; 
    color: #888; 
} 

Jede Idee, warum und wie kann ich das beheben?

Answer 1

Wenn Sie Spalten werden in einem Raster zu verwenden, müssen Sie innerhalb einer Zeile die Spalten haben:

<div class="row"> 
    <div class="col-md-4"> 
      stuff 
    </div> 
    <div class="col-md-4"> 
      more stuff 
    </div> 
</div>
