Bootstrap: 缩略图正在产生水平溢出

Question

我已经尝试修复这个问题 2 个小时了，我什至重写了整个网站，只是为了看看是什么造成了溢出，并且刚刚意识到，当我添加我的 "thumbnail" 组件时，它创建了一个水平溢出真是令人沮丧。

这是我网站的精简版，尝试删除缩略图部分，您会发现一切正常。但随之而来的是溢出。

怎么回事？

Answer 1

在您的行标记前添加一个容器：

<section>
    <div class="container">
        <div class="row">
            <div class="thumbnail"></div>
        </div>
    </div>
</section>

因为容器会自动给你 padding 和 margin 参数。
