卡片 div 的 HTML 水平滚动条

Question

我想为卡片类实现一个水平滚动条，如本例所示。我试过，overflow-x:scroll但没有走运。任何人都可以建议我如何实现滚动条以使卡片水平流动？谢谢

.card {
  float: left;
  width: 33.333%;
  padding: .75rem;
  margin-bottom: 2rem;
  border: 0;
}

.card > img {
  margin-bottom: .75rem;
}

.card-text {
  font-size: 85%;
}

<div class="container">
  <div class="row">
    <div class="card">
      <img src="http://placehold.it/200x150">
      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
    </div>

使用FlexBox它制作水平滚动条非常容易。当父母是display: flex;然后float将没有effectin child element。检查代码段它是如何工作的。

.row{
  align-items: stretch;
  display: flex;
  flex-direction: row;
  flex-wrap: nowrap;
  overflow-x: auto;
  overflow-y: hidden;
}
.card {
  /*float: left;*/
  max-width: 33.333%;
  padding: .75rem;
  margin-bottom: 2rem;
  border: 0;
  flex-basis: 33.333%;
  flex-grow: 0;
  flex-shrink: 0;
}

.card > img {
  margin-bottom: .75rem;
  width: 100%;
}

.card-text {
  font-size: 85%;
}

<div class="container">
  <div class="row">
    <div class="card">
      <img src="https://picsum.photos/300/200">
      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
