For example

[wrap=link-button][Link Text](http://meta.discourse.org)[/wrap]

renders as

Link Text

and the markup is

<div class="d-wrap" data-wrap="link-button">
  <p>
    <a href="http://meta.discourse.org">Link Text</a>
  </p>
</div>

and you can then style it in CSS using

[data-wrap="link-button"] {
  a {
    // styles for the link
  }
}

You can change [wrap=link-button] to any value you want like

[wrap=custom-button]
or
[wrap=home-link]
or
[wrap=foobar]

and then use that to target the link like the example above.

I added this feature a while back and realised I didn’t post about it. You can now use a special syntax in markdown to have it cooked and usable in theme components without having to write a plugin.

// wrapped in div.d-wrap
[wrap=baz foo=bar]Content[/wrap]

// wrapped in div.d-wrap
[wrap=baz foo=bar]
Content
[/wrap]

// wrapped in div.d-wrap
[wrap=baz foo=bar]
[/wrap]

// this one will be rendered as a span.d-wrap instead of a div.d-wrap
a [wrap=baz]Content[/wrap] b

The name of the component will be added as a data-attribute: data-wrap="baz" and every properties will also be data-attributes: data-foo="bar" on the element.
