The default grid system provided in Bootstrap utilizes 12 columns that render out at widths of 724px, 940px (default without responsive CSS included), and 1170px. Below 767px viewports, the columns become fluid and stack vertically.
<div class="row"> <div class="span4">...</div> <div class="span8">...</div> </div>
As shown here, a basic layout can be created with two "columns", each spanning a number of the 12 foundational columns we defined as part of our grid system.
<div class="row"> <div class="span4">...</div> <div class="span4 offset4">...</div> </div>
With the static (non-fluid) grid system in Bootstrap, nesting is easy. To nest your content, just add a new .row and set of .span* columns within an existing .span* column.

电视剧、电影一般由视频网站采购和买断,而网大和网剧对视频网站收费也是一个很好的补充,作为PGC的延伸,由专业的内容生产者提供给视频网站,之后进行付费分账或者保底分账。 我们总是在抱怨我们的教育体制如何如何与美国有差距,其实研究比较下来,两国最大的差距就在于教育中的习和用,中国的教育更重视知识的纸面考核,美国的教育更倾向于知识的实践应用。
早几年互联网的口号是免费,在我看来这是一个巨大的谎言,免费是为了更好地付费,几乎所有游戏公司都因为免费获得了巨大利润,未来,付费会是一个明显的趋势。一定是已经想到了怎么样把它卖好,想到了别人怎么会喜欢这个东西。

Bootstrap doesn't automatically include these media queries, but understanding and adding them is very easy and requires minimal setup. You have a few options for including the responsive features of Bootstrap:
Why not just include it? Truth be told, not everything needs to be responsive. Instead of encouraging developers to remove this feature, we figure it best to enable it.
