Special AngularJS Admin Theme for small and medium webapp with very clean and aesthetic style and feel.
Bootstrap includes a responsive, mobile first fluid grid system that appropriately scales up to 12 columns as the device or viewport size increases. It includes predefined classesfor easy layout options, as well as powerfulmixins for generating more semantic layouts.
Grid systems are used for creating page layouts through a series of rows and columns that house your content. Here's how the Bootstrap grid system works:
.container
(fixed-width) or .container-fluid
(full-width) for proper alignment and padding..row
and .col-xs-4
are available for quickly making grid layouts. Less mixins can also be used for more semantic
layouts.
padding
. That padding is offset in rows for the first and last column via negative margin on
.row
s.
.col-xs-4
.
.col-md-*
class to an element will not only affect its styling on medium devices but also on large devices if a .col-lg-*
class
is not present.
See how aspects of the Bootstrap grid system work across multiple devices with a handy table.

Grid classes apply to devices with screen widths greater than or equal to the breakpoint sizes, and override grid classes targeted at smaller devices. Therefore, applying any
.col-md-
class to an element will not only affect its styling on medium devices but also on large devices if a
.col-lg-
class is not present.
Using a single set of
.col-md-*
grid classes, you can create a default grid system that starts out stacked on mobile devices and tablet devices (the extra small to small range) before
becoming horizontal on desktop (medium) devices. Place grid columns in any
.row
.
Don't want your columns to simply stack in smaller devices? Use the extra small and medium device grid classes by adding
.col-xs-*
.col-md-*
to your columns. See the example below for a better idea of how it all works.
With the four tiers of grids available you're bound to run into issues where, at certain breakpoints, your columns don't clear quite right as one is taller than the other. To fix
that, use a combination of a
.clearfix
and our responsive utility classes.
Move columns to the right using
.col-md-offset-*
classes. These classes increase the left margin of a column by
*
columns. For example,
.col-md-offset-4
moves
.col-md-4
over four columns.
