# Heading
The Heading extension adds support for headings of different levels. Headings are rendered with `<h1>`, `<h2>`, `<h3>`, `<h4>`, `<h5>` or `<h6>` HTML tags. By default all six heading levels (or styles) are enabled, but you can pass an array to only allow a few levels. Check the usage example to see how this is done.
Type <code>#&nbsp;</code> at the beginning of a new line and it will magically transform to a heading, same for <code>##&nbsp;</code>, <code>###&nbsp;</code>, <code>####&nbsp;</code>, <code>#####&nbsp;</code> and <code>######&nbsp;</code>.
