Since bootstrap removed the *fluid css classes in v3.0, I couldn't find a way to build a two-column fluid layout. The goal is to achieve a layout similar to the Fluid Layout example in their old documantation: http://getbootstrap.com/2.3.2/scaffolding.html#layouts
The grid in Bootstrap 3 is now fluid by default (http://getbootstrap.com/getting-started/#migration-dropped). You just need to use .row
and .container
..
<div class="container">
<div class="row">
<div class="col-md-2">
Sidebar content
</div>
<div class="col-md-10">
Body content
</div>
</div>
</div>
This however will not be 100% width. If you want 100% width you can do something like this.. http://www.bootply.com/86324
UPDATE: 3.0.1 and later use container-fluid
for full width.
