Default grid system 12 columns with a responsive twist
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.
自从卡塔尔老板于2011年入主俱乐部以来，从来没有一名球员以这种方式被停赛这么长时间。但现在这样的情况发生了，并且发生在‘历史最佳球员的身上。
<div class="row">
<div class="span6">
Level 1 column
<div class="row">
<div class="span3">Level 2</div>
<div class="span3">Level 2</div>
</div>
</div>
</div>
Fluid grid system 12 responsive, percent-based columns
Nesting with fluid grids is a bit different: the number of nested columns doesn't need to match the parent. Instead, your columns are reset at each level because each row takes up 100% of the parent column.
<div class="row-fluid">
<div class="span12">
Level 1 of column
<div class="row-fluid">
<div class="span6">Level 2</div>
<div class="span6">Level 2</div>
</div>
</div>
</div>

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:
- 宣武区
- 九龙坡区
- 大埔区
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.

ESPN认为，巴黎圣日耳曼对自己的明星球员一向宽容，不怎么守纪律的内马尔就逃脱了大量处罚。自从卡塔尔老板于2011年入主俱乐部以来，从来没有一名球员以这种方式被停赛这么长时间。
但这一次俱乐部需要通过惩罚梅西来立威。俱乐部对此予以谴责，并全力支持自家球员和管理层，以及所有被这些可耻行为攻击的人。
