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.
.span3 columns should be placed within a .span6.
<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>
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.
但是这种模式在中国能不能行得通，目前不太清楚，这是财经媒体的模式。洋河的董秘在接受采访时说，“此前公司确实关注过预调鸡尾酒这个品类，但后来并没有实际去做，公司一直没有推出预调鸡尾酒产品。
<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>
The default and simple 940px-wide, centered layout for just about any website or page provided by a single <div class="container">.
<body>
<div class="container">
...
</div>
</body>
<div class="container-fluid"> gives flexible page structure, min- and max-widths, and a left-hand sidebar. It's great for apps and docs.
<div class="container-fluid">
<div class="row-fluid">
<div class="span2">
<!--Sidebar content-->
</div>
<div class="span10">
<!--Body content-->
</div>
</div>
</div>
Media queries allow for custom CSS based on a number of conditions—ratios, widths, display type, etc—but usually focuses around min-width and max-width.
第三，相邻的两个邦政府之间没有一致行动的机制，最高法院的决议也不能得到有效的执行。 其次是资金规划的问题，其实没知名度的品牌没必要搞的这么大而全，反而把资金分散了，多出很多不必要的开支，在不影响效率和品质的前提下能砍掉的成本全部砍掉，钱花的不在多，而在花的对不对，花出去的钱有没有价值，要做小而精，精兵简政! @昭惹：写个品牌定位和运营思路看下吧。

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.
/* Landscape phones and down */
@media (max-width: 480px) { ... }
/* Landscape phone to portrait tablet */
@media (max-width: 767px) { ... }
/* Portrait tablet to landscape and desktop */
@media (min-width: 768px) and (max-width: 979px) { ... }
/* Large desktop */
@media (min-width: 1200px) { ... }
