将边框线添加到引导网格

Question

在此输入图像描述我有一个使用col-md-3类创建的网格，它有3列：

<div ng-repeat='(key, value) in permissionsViewContent' class="row">
    <div class="tree_content_permissions_title">
        <span> {{key}}</span>
    </div>
    <div ng-repeat="val in value"
        class="col-md-3 tree_content_permissions">
        <label class="checkbox"> <input type="checkbox"> 
            {{val}}
        </label>
    </div>
</div>

此网格是根据值列表创建的。我希望我的网格在网格中的每一行后都有边框线。我怎么能用css来做呢？

谢谢，
