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.

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.
