This is how you can achieve your desired setup with Bootstrap 3:
<div class="container-fluid">
<div class="row"> <!-- Give this div your desired background color -->
<div class="container">
<div class="row">
<div class="col-md-12">
... your content here ...
</div>
</div>
</div>
</div>
</div>
The container-fluid
part makes sure that you can change the background over the full width. The container
part makes sure that your content is still wrapped in a fixed width.
This approach works, but personally I don't like all the nesting. However, I haven't found a better solution so far.
