Using container class in Tailwind CSS

The container class sets the max-width of an element to match the min-width of the current breakpoint. This is useful if you’d prefer to design for a fixed set of screen sizes instead of trying to accommodate a fully fluid viewport.

Note that unlike containers you might have used in other frameworks, Tailwind’s container does not center itself automatically and does not have any built-in horizontal padding.

<div class="container mx-auto px-4">
  <!-- ... -->
</div>
