The <code>container</code> is a simple utility element that allows you to
<strong>center</strong> content on larger viewports. It can be used in any
context, but mostly as a <strong>direct child</strong> of one of the
following:
</p>
<ul>
<li><code>navbar</code></li>
<li><code>hero</code></li>
<li><code>section</code></li>
<li><code>footer</code></li>
</ul>

{% include docs/elements/anchor.html name="Default behavior" %}
<div class="content">
<p>
By default, the <code>container</code> will only be activated from the
<code>$desktop</code> breakpoint. It will increase its
<code>max-width</code> after reaching the <code>$widescreen</code> and
<code>$fullhd</code> breakpoints.
</p>
<p>
The container's <strong>width</strong> for each
<strong>breakpoint</strong> is the result of:
<code>$device - (2 * $gap)</code>. The <code>$gap</code> variable has a
default value of <code> 32px</code> but can be modified.
</p>
<p>This is how the container will behave:</p>
<ul>
<li>
on <code>$desktop</code> it will have a maximum width of
<strong>960px</strong>.
</li>
<li>
on <code>$widescreen</code> it will have a maximum width of
<strong>1152px</strong>.
</li>
<li>
on <code>$fullhd</code> it will have a maximum width of
<strong>1344px</strong>.
</li>
</ul>
<p>
The values <strong>960</strong>, <strong>1152</strong> and
<strong>1344</strong> have been chosen because they are divisible by both
<strong>12</strong> and <strong>16</strong>.
</p>

{% highlight html -%} {{- container_example -}} {%- endhighlight %}
<!-- -->
{% include docs/elements/anchor.html name="Widescreen or FullHD only" %}
<div class="content">
<p>
With the two modifiers <code>is-widescreen</code> and
<code>is-fullhd</code>, you can have a <em>fullwidth</em> container
<strong>until</strong> those specific breakpoints.
</p>
</div>
<div class="bd-example is-fullwidth">{{ container_widescreen_example }}</div>
{% highlight html -%} {{- container_widescreen_example -}} {%- endhighlight %}

<p>
Sometimes, you might want a <strong>narrow</strong> container on larger
viewports. That's why Bulma provides 3 modifier classes:
</p>
<ul>
<li>
<code>.container.is-max-tablet</code> will behave like a tablet container
</li>
<li>
<code>.container.is-max-desktop</code> will behave like a desktop
container
</li>
<li>
<code>.container.is-max-widescreen</code> will behave like a widescreen
container
</li>
</ul>
</div>
<div class="bd-example is-fullwidth">{{ container_max_tablet_example }}</div>

<div class="bd-example is-fullwidth">{{ container_max_desktop_example }}</div>
{% highlight html -%} {{- container_max_desktop_example -}} {%- endhighlight %}
<div class="bd-example is-fullwidth">

{% highlight html -%} {{- container_max_widescreen_example -}} {%- endhighlight
%}
<!-- -->
{% include docs/elements/anchor.html name="Absolute maximum width" %}
<div class="content">
<p>
If you want to change the maximum width of <strong>all</strong> containers,
you can do so by updating the values of the
<code>$container-max-width</code> Sass variable.
</p>
<p>
By default, the <code>$fullhd</code> breakpoint value is used to calculate
the <strong>absolute</strong> maximum width of the <code>container</code>.
Simply change it to a smaller value like <code>$widescreen</code>,
<code>$desktop</code>, or any value in <strong>pixels</strong>.
</p>
</div>
<!-- -->
{% include docs/elements/anchor.html name="Fluid container" %}
<div class="content">
<p>
If you don't want to have a maximum width but want to keep the 32px margin
on the left and right sides, add the
<code>is-fluid</code> modifier:
</p>
</div>
<div class="bd-example is-fullwidth">{{ container_fluid_example }}</div>
