The default grid system provided as part of Bootstrap is a 940px-wide, 12-column grid.

<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">
<div class="span6">Level 2</div>
<div class="span6">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.

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.

| Variable | Default value | Description |
|---|---|---|
@gridColumns | 12 | Number of columns |
@gridColumnWidth | 60px | Width of each column |
@gridGutterWidth | 20px | Negative space between columns |
@siteWidth | Computed sum of all columns and gutters | Counts number of columns and gutters to set width of the .container-fixed() mixin |
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 无锡婚礼策划团购_360团购导航. If you're adding more columns, be sure to add the CSS for those in grid.less.

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: 768px) { ... }
// Portrait tablet to landscape and desktop
@media (min-width: 768px) and (max-width: 980px) { ... }
// Large desktop
@media (min-width: 1200px) { .. }
