如何显示两张牌水平与相等的高度使用引导

Question

我使用bootstrap。需要放置两张等高的牌。每张卡片都放在colx -6中。卡片包含文本和按钮。当我使用col-height col-xs-6 card时，两个卡都连接在一起。可以请你帮我一下吗?

<div class="row">
      <div class="row-height">
        <div class="col-height col-middle col-xs-6 card">
          <div class="row">
            <div class="col-xs-12 text-center">
              <h3 class="heading-s1">Login</h3>
            </div>
            <div class="col-xs-12 text-center">
              <a href="javascript:void(0);" class="btn big-btn no-border red-background unstyle-anchor" style="padding: 13px 50px;">Login!</a>
            </div>
          </div>
        </div>
        <div class="col-height col-middle col-xs-6 card">
          <div class="row">
            <div class="col-xs-12 text-center">
              <h3 class="heading-s1">Sign UP</h3>
            </div>
            <div class="col-xs-12 text-center">
              <a href="javascript:void(0);" class="btn big-btn no-border red-background unstyle-anchor" style="padding: 13px 50px;">Sign Up!</a>
            </div>
          </div>
        </div>
      </div>
    </div>

这是你想要的吗?

.row应包入.container

.card {
  border: 1px solid black;
  margin: 10px;
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet" />
<div class="container">
  <div class="row-height">
    <div class="row">
      <div class="col-height col-middle col-xs-5 pull-left card">
        <div class="col-xs-12 text-center">
          <h3 class="heading-s1">Login</h3>
        </div>
        <div class="col-xs-12 text-center">
          <a href="javascript:void(0);" class="btn big-btn no-border red-background unstyle-anchor" style="padding: 13px 50px;">Login!</a>
        </div>
      </div>
      <div class="col-height col-middle col-xs-5 pull-right card">
        <div class="col-xs-12 text-center">
          <h3 class="heading-s1">Sign UP</h3>
        </div>
        <div class="col-xs-12 text-center">
          <a href="javascript:void(0);" class="btn big-btn no-border red-background unstyle-anchor" style="padding: 13px 50px;">Sign Up!</a>
