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.

<div class="row">

The fluid grid system uses percents for column widths instead of fixed pixels. It also has the same responsive variations as our fixed grid system, ensuring proper proportions for key screen resolutions and devices.
或者咱们解释的简单粗暴一点,这就是个幸存者偏差的故事:你看到的都是成功,你没看到的都是失败。 今日头条CEO张一鸣在2016年宣布将投入10亿元贴补短视频创作者,并通过海外收购Flipagram和取得视听牌照完善该领域布局。
<div class="row-fluid"> <div class="span4">...</div> <div class="span8">...</div> </div>
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>

Built into Bootstrap are a handful of variables for customizing the default 940px grid system, documented above. All variables for the grid are stored in variables.less.
Modifying the grid means changing the three @grid* variables and recompiling Bootstrap. Change the grid variables in variables.less and use one of the 王金平宣布访陆祭祖:共同血脉不因族群党派改变. If you're adding more columns, be sure to add the CSS for those in grid.less.
评委杨飞(神州优车CMO)则表示所谓的“名气大”并不是选择的标准,而是更加关注案例的这两个特征:1.基于移动端技术和新鲜事物的营销手段;2.品效合一,效果转化明显(即便没有数据根据本人和身边朋友也能亲证的)。第一类是数量众多的中小投资机构。

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.

@media (max-width: 480px) { ... }
/* Landscape phone to portrait tablet */
