如何在不向下移动的情况下将列从三减少到两 - 引导

Question

我正在尝试将这段 html/css http://bootsnipp.com/snippets/featured/grid-columns-divider 用作行分隔符。然而;当我试图摆脱一列并将其作为具有 25%/75% 拆分的 2 列时，它会出现故障并使其低于它并且行分隔符消失。另外，如何让分线器不像现在那样靠近顶部，我希望顶部有一个间隙。

你可以看看下面修改后的snippet。

我已经添加了一个类 .pb-15，以便按照您的要求在顶部分隔线处留出一个空隙。

/* Tablet and bigger */
@media ( min-width: 768px ) {
    .grid-divider {
        position: relative;
        padding: 0;
    }
    .grid-divider>[class*='col-'] {
        position: static;
    }
    .grid-divider>[class*='col-']:nth-child(n+2):before {
        content: "";
        border-left: 1px solid #DDD;
        position: absolute;
        top: 0;
        bottom: 0;
    }
    .col-padding {
        padding: 0 15px;
    }
}

.pb-15 {
  padding-bottom: 15px!important;
 }

<div class="container">
    <div class="page-header pb-15">
        <h3>Add the (.grid-divider) class to any row to separate grid columns with equal height lines.</h3>
    </div>
    <div class="row grid-divider">
    <div class="col-sm-3">
      <div class="col-padding">
        <h3>Column 1</h3>
