<!-- The defer is not necessary for autoloading, but is necessary for the
script at the bottom to work as a Quine. -->
<script src="https://cdn.rawgit.com/google/code-prettify/master/loader/run_prettify.js?autoload=true&skin=sunburst&lang=css" defer="defer"></script>

<h1>Making Quines Prettier</h1>
<p>
Below is the content of this page prettified. The <code><pre></code>
element is prettified because it has <code>class="prettyprint"</code> and
because the sourced script loads a JavaScript library that styles source
code.
</p>
<p>
The line numbers to the left appear because the preceding comment
<code><?prettify lang=html linenums=true?></code> turns on
line-numbering and the
<a href="https://cdn.rawgit.com/google/code-prettify/master/styles/index.html">stylesheet</a>
(see <code>skin=sunburst</code> in the <code><script src></code>)
specifies that every fifth line should be numbered.
</p>
<!-- Language hints can be put in XML application directive style comments. -->
<?prettify lang=html linenums=true?>
<pre class="prettyprint" id="quine" style="border:4px solid #88c"></pre>
<script>//<![CDATA[
(function () {
function html(s) {
return s.replace(/&/g, '&').replace(/</g, '<').replace(/>/g, '>');
}
var quineHtml = html(
'<!DOCTYPE html>\n<html>\n'
+ document.documentElement.innerHTML
+ '\n<\/html>\n');
// Highlight the operative parts:
quineHtml = quineHtml.replace(
/<script src[\s\S]*?><\/script>|<!--\?[\s\S]*?-->|<pre\b[\s\S]*?<\/pre>/g,
'<span class="operative">$&</span>');
document.getElementById("quine").innerHTML = quineHtml;
