# Making Quines Prettier

Below is the content of this page prettified. The `<pre>` element is prettified because it has `class="prettyprint"` and because the sourced script loads a JavaScript library that styles source code.

The line numbers to the left appear because the preceding comment `<?prettify lang=html linenums=true?>` turns on line-numbering and the stylesheet (see `skin=sunburst` in the `<script src>`) specifies that every fifth line should be numbered.
