### mj-hero

Displays a hero image and behaves like an `mj-section` tag with a single `mj-column` tag.

The `background-height` and `background-width` attributes are mandatory and it's best to use an image with width the same as the `mj-body` (`width="600px"` by default) and height the same or larger than the `height` of `mj-hero`.

Use `background-color` to provide a fallback color in case an email client doesn't support `background-url`.

<div class="alert alert-note" role="alert">
  <p>Note</p>
  <p>The <code>height</code> attribute is only required for <code>mode="fixed-height"</code>.</p>
</div>
