Float 无法使用 Twitter-Bootstrap

Question

我在寻找答案，但每次尝试使用这些答案时，我仍然没有得到想要的结果。我正在使用 bootstrap 缩略图元素并试图让它们像在 bootstrap 网站上那样相互浮动。尝试将它们塞入以分隔 divs。尝试将它们全部塞进一个 div。什么都不起作用。有任何想法吗？如有任何意见，我们将不胜感激。

这是代码的 link：http://jsbin.com/paregopuni/1/edit?html,css,output

#announcements {
    width: 70%;
    margin-left: auto;
    margin-right: auto;
    margin-top: 3em;
}

.jumbotron p {
    margin: 1em;
}

.jumbotron h1 {
    margin: 0.5em;
}


.floatleft {
    float:  left;
}

.clear {
  clear: both;
}

Answer 1

您的代码不起作用，因为您将缩略图放在不同的两行中，它们必须在同一行中 row。 http://jsbin.com/dekefidawo/1/edit

<div class="row">
  <div class="col-sm-6 col-md-4">
    <div class="thumbnail">
    </div>
  </div>
  <div class="col-sm-6 col-md-4">
    <div class="thumbnail">
    </div>
  </div>
</div>
