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.
据法国《队报》此前报道，由于本月1日缺席球队训练并前往沙特进行个人活动，梅西被俱乐部处以为期两周的停赛、停训、停薪的三停处罚。尽管俱乐部表态支持自家球员，但梅西和巴黎圣日耳曼之间的裂痕已非常明显。
<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>

如果梅西在今夏离开巴黎，可供他选择的下家有很多。据法国《队报》此前报道，由于本月1日缺席球队训练并前往沙特进行个人活动，梅西被俱乐部处以为期两周的停赛、停训、停薪的三停处罚。

据法新社4日报道，数百名巴黎圣日耳曼球迷聚集在俱乐部门口，用口号表达对球队现状和梅西的不满。如果梅西在今夏离开巴黎，可供他选择的下家有很多。

本赛季法甲联赛中，梅西已收获15粒进球、15次助攻，帮助球队在法甲联赛还剩5轮的情况下以5分优势领跑积分榜。法新社称，梅西在最近的比赛中经常遭遇自家球迷的嘘声，球迷认为俱乐部签约梅西只是为了追求超级巨星效应，而并非打算建立一支真正有竞争力的球队。
但在欧冠赛场上，巴黎圣日耳曼已连续两年折戟16强。据法国《队报》此前报道，由于本月1日缺席球队训练并前往沙特进行个人活动，梅西被俱乐部处以为期两周的停赛、停训、停薪的三停处罚。
| Label | Layout width | Column width | Gutter width |
|---|---|---|---|
| Smartphones | 480px and below | Fluid columns, no fixed widths | |
| Smartphones to tablets | 767px and below | Fluid columns, no fixed widths | |
| Portrait tablets | 768px and above | 42px | 20px |
| Default | 980px and up | 60px | 20px |
| Large display | 1200px and up | 70px | 30px |
目前并不清楚梅西是擅自缺席训练还是与俱乐部沟通有误会，在ESPN看来，这些并不重要，梅西注定不会留守巴黎。

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:
- 眼球先生
- 林埈永
- 蟑螂
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.
