Bootstrap：容器扩展似乎没有理由

Question

我一直在使用Bootstrap 3.3.1开发网站。我的一个页面有一个注册表单。出于某种原因，这种形式变得非常长，超过1000px到页面底部。我没有更改此页面使用的任何代码，因为我上次检查它是好的。

这就是网站现在的样子。

我对如何发生这种情况感到困惑。任何帮助都会有很大的帮助。

Answer 1

我最终浏览了网站上运行的所有代码部分。不知何故，我的谷歌分析代码导致了它。我不确定为什么，为什么它不影响网站的任何其他部分，但一旦我删除它，一切都恢复正常。关于为什么会发生这种情况的任何想法？

Answer 2

在bootstrap.min.css中的此规则中找到它：

.progress-bar {
    background-color: #337ab7;
    box-shadow: 0 -1px 0 rgba(0, 0, 0, 0.15) inset;
    color: #fff;
    float: left;
    font-size: 12px;
    height: 100%;
    line-height: 20px;
    text-align: center;
    transition: width 0.6s ease 0s;
    width: 0;
}

height: 100%;是原因。您可以使用：

进行修复

.progress-bar { height: auto; }
