Bootstrap 'col'标签不会将文章拉到尽可能多的行中

我第一次尝试使用Bootstrap并且在实现'col'标记时遇到问题,以便它适合视口允许的内容/行数 . 以下是我的基本标记 .

我相信我遵循正确的顺序,使用div / section标签,类为“容器文本中心”,然后是div / class =“row”标签,然后是一个类别为“col”的文章 . 我的理解是,如果“col”标签没有/没有设置列宽,那么它将尝试创建一列六列或尽可能多的列,这取决于单词中字符的字符如何列将允许内容中断/显示/呈现 .

我相信我所做的应该是有效的 . 我正在按照enter link description here中的lynda视频使用Bootstrap v4 beta 0.6

我希望有人可以解释/指出我在哪里搞砸了 . 我已经检查了Stack Overflow的类似问题,虽然我发现了类似的问题,但他们都说的是col-size-#而不仅仅是'row'类本身 .

需要进行一些小的修正,以确保达到您想要的效果 .

  • <row> 元素更改为 <div class="row">

  • 确保加载正确版本的bootstrap

bootstrap的宽度是12(它使用网格) . 所以,如果你想要6篇文章,你必须这样做:

<article class="col-lg-2">
