This fixes an issue where an `<aside>` element with a single line would
look really weird and boxed in, compared to an `<aside>` element with
multiple lines.
This has been bugging me for a while and I finally looked up how
Benjamin Hollon handles this on his blog. Here's a good example:
https://benjaminhollon.com/musings/wireless-is-a-lie/
. When compared with my own blog, I noticed the additional `<p>` tag in
Ben's code and everything became clear. If we have multiple lines, Hugo
will automatically introduce paragraphs and the formatting will be
correct. For a single line however, Hugo would assume that it was part
of the content surrounding it. That's why the surrounding box of an
`<aside>` element with a single line would look squashed.
The README has been updated to show a code example of both, including an
exemplary screenshot.
Since Hugo 0.55, we have to use `markdownify` in shortcodes that contain
HTML elements. At least we have to, if we want to render markdown code
inside the HTML element.
To use the `<aside>` element, we have to wrap our content in an
`<article>` tag.
This fixes#4.
