中心多個自舉列當小於12列

Question

<div class="row"> 
    <div ng-repeat="tile in tiles" class="col-md-3"></div> 
</div> 

如何確保這些引導列始終居中，即使只有2列？

Answer 1

添加row-center類行和col-center對col-MD-3這樣：

<div class="row row-center"> 
    <div ng-repeat="tile in tiles" class="col-md-3 col-center"></div> 
</div> 

.row-center { 
    text-align:center; 
} 

.col-center { 
    display:inline-block; 
    float:none; 
}
