To wrap your content in a responsive container use the <mui-container>
element:
<mui-container>
<!--
Container is centered on page with 15px of
padding on either side. The inner width is
fluid for small viewports and has a max
width for larger dimensions:
* 570px (≥ 544px)
* 740px (≥ 768px)
* 960px (≥ 992px)
* 1170px (≥ 1200px)
-->
</mui-container>
To wrap your content in a fluid container add a fluid
attribute:
<mui-container fluid>
<!--
Container is centered on page with 15px of
padding on either side. The inner width is
fluid for all viewport widths.
-->
</mui-container>
