我的引导页面上有这个令人恼火的水平滚动。无法弄清楚是什么导致它出现这样的行为或该怎么办？

As per Bootstrap 3 文档 http://getbootstrap.com/css/#grid:
行必须放置在 .container （固定宽度）或 .container-fluid （全角）内，以便正确对齐和填充。
因此，添加类container给你的.wrapper元素。
更新的示例 http://jsfiddle.net/jnjs2Lq5/
<div class="wrapper container">
<div class="row">
...
</div>
</div>
至于解释，.row班级有-15px每边都有边距。
.row {
margin-right: -15px;
margin-left: -15px;
}
The .container类有效地用以下内容取代了它：
.container {
padding-right: 15px;
padding-left: 15px;
margin-right: auto;
margin-left: auto;
}
除了阅读Bootstrap 3 文档 http://getbootstrap.com/，我建议阅读这篇文章“Bootstrap 3 网格工作原理背后的微妙魔力 http://www.helloerik.com/the-subtle-magic-behind-why-the-bootstrap-3-grid-works".
