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.

<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.
这种方式确实可以在短时间内营造出一种“创业有成”的假象，但如果创业项目没有优质产品为保障，最后难逃被“取关”的命运。 网站日志类型: 一、Apache日志——Linux系统服务器日志 二、iis日志——Windows系统服务器日志 不管是哪种日志，主要看懂以下四点: 被访问的文件地址——cs-uri-stem 搜索引擎蜘蛛或者用户浏览器——cs(User-Agent) 访问者的IP——c-ip 访问状态码——sc-status 网站日志的获取流程(以莆田蓝韵公司空间为例：服务器操作系统是Windows) 第一步：登录空间后台——控制面板——WebLog日志下载 第二步：把下载的日志用EditPlus打开,删除一些没用的，如下图所示，整理好，保存为.txt文档(之所以保存为txt文档，是为下一步做准备，因为excel表格导入数据只能是txt文档，别的格式不支持) 第三步：用excel表格导入，表格选中在第一行第一列位置，然后按照以下步骤一步步完成就可以了。

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.
