Как создать нижний колонтитул внизу компонента Bootstrap

Я пытаюсь работать с некоторыми CSS, и я использую Bootstrap и компонентные "карты"

Когда у вас есть их в классе под названием "card-deck", вы можете сгруппировать их на все одинаковые высоты. Но когда один длиннее другого, фактические нижние колонтитулы в самих карточках не выравниваются по нижней части карты.

Есть ли способ легко заставить нижний колонтитул снизу на более короткой карте?

MY FIDDLE

.row {
  padding-top: 50px;
}

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.2/js/bootstrap.min.js"></script>
<link href="#" onclick="location.href='https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.2/css/bootstrap.min.css'; return false;" rel="stylesheet" />

<div class="container">
  <div class="row">
    <div class="card-deck-wrapper">
      <div class="card-deck">
        <div class="card text-xs-center">
          <div class="card-header">
            Featured
          </div>
          <div class="card-block">
            <h4 class="card-title">Special title treatment</h4>
            <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
            <a href="#" class="btn btn-primary">Go somewhere</a>
          </div>
          <div class="card-footer text-muted">

Ответ 1

использовать position:absolute для нижнего колонтитула

.row {
  padding-top: 50px;
}
.card-footer{
position:absolute;
  bottom:0;
  width:100%;
}
.card-deck .card{
  padding-bottom:50px;
  }

Ответ 2

У меня была та же проблема, и я не мог найти решение в течение нескольких дней. Затем я изучил flexbox. Вы можете решить это, изменив

<div class="card">...</div>

<div class="card h-100 d-flex flex-column justify-content-between">...</div>

Он работает с Bootstrap 4, я не знаю о других версиях.

Или просто используйте правильные классы Bootstrap, card-body card-block вместо блока card-block

.row {
  padding-top: 50px;
}
