Basic fluid grid HTML

Make any row "fluid" by changing .row to .row. The column classes stay the exact same, making it easy to flip between fixed and fluid grids.

<div class="row">  <div class="col-md-4">...</div>  <div class="col-md-8">...</div></div>

Fluid offsetting

Operates the same way as the fixed grid system offsetting: add .offset* to any column to offset by that many columns.

4 offset 4
3 offset 3
3 offset 3
6 offset 6
<div class="row">  <div class="col-md-4">...</div>  <div class="col-md-4 offset2">...</div></div>

Fluid nesting

Fluid grids utilize nesting differently: each nested level of columns should add up to 12 columns. This is because the fluid grid uses percentages, not pixels, for setting widths.

Fluid 12
Fluid 6
Fluid 6
Fluid 6
Fluid 6
<div class="row">  <div class="col-md-12">    Fluid 12    <div class="row">      <div class="col-md-6">        Fluid 6        <div class="row">          <div class="col-md-6">Fluid 6</div>          <div class="col-md-6">Fluid 6</div>        </div>      </div>      <div class="col-md-6">Fluid 6</div>    </div>  </div></div>

About responsive Bootstrap

Responsive devices

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.

  • Modify the width of column in our grid
  • Stack elements instead of float wherever necessary
  • Resize headings and text to be more appropriate for devices

Use media queries responsibly and only as a start to your mobile audiences. For larger projects, do consider dedicated code bases and not layers of media queries.

Supported devices

Bootstrap supports a handful of media queries in a single file to help make your projects more appropriate on different devices and screen resolutions. Here's what's included:

Label Layout width Column width Gutter width
Large display 1200px and up 70px 30px
Default 980px and up 60px 20px
Portrait tablets 768px and above 42px 20px
Phones to tablets 767px and below Fluid columns, no fixed widths
Phones 480px and below Fluid columns, no fixed widths
/* Large desktop */
@media (min-width: 1200px) { ... }

/* Portrait tablet to landscape and desktop */
@media (min-width: 768px) and (max-width: 979px) { ... }

/* Landscape phone to portrait tablet */
@media (max-width: 767px) { ... }

/* Landscape phones and down */
@media (max-width: 480px) { ... }

Responsive utility classes

For faster mobile-friendly development, use these utility classes for showing and hiding content by device. Below is a table of the available classes and their effect on a given media query layout (labeled by device). They can be found in responsive.less.

Class Phones 767px and below Tablets 979px to 768px Desktops Default
.visible-phone Visible
.visible-tablet Visible
.visible-desktop Visible
.hidden-phone Visible Visible
.hidden-tablet Visible Visible
.hidden-desktop Visible Visible

When to use

Use on a limited basis and avoid creating entirely different versions of the same site. Instead, use them to complement each device's presentation. Responsive utilities should not be used with tables, and as such are not supported.
