title: Containers
Bootstrap requires a containing element to wrap site contents and house our grid system. Choose from the fixed or fluid width variation.
Use `.container` for a responsive fixed width container. This will center content withing the viewport and apply the appropriate `width` for a given device size. **Containers *can* be nested, but be aware that most layouts don't require it.**
{% highlight html %}
<div class="container">
...
</div>
{% endhighlight %}
Use `.container-fluid` for a full width container, spanning the entire width of the viewport.
<div class="container-fluid">
