title: Syntax Highlighting Post
description: "Demo post displaying the various ways of highlighting code in Markdown."
tags: [sample post, code, highlighting]

[Syntax highlighting](http://en.wikipedia.org/wiki/Syntax_highlighting) is a feature that displays source code, in different colors and fonts according to the category of terms. This feature facilitates writing in a structured language such as a programming language or a markup language as both structures and syntax errors are visually distinct. Highlighting does not affect the meaning of the text itself; it is intended only for human readers.
### Pygments Code Blocks
To modify styling and highlight colors edit `/assets/less/pygments.less` and compile `main.less` with your favorite preprocessor. Or edit `main.css` if that's your thing, the classes you want to modify all begin with `.highlight`.
{% highlight css %}
#container {
float: left;
margin: 0 -240px 0 0;
width: 100%;
}
{% endhighlight %}
Line numbering enabled:
{% highlight html linenos %}
{% raw %}
<nav class="pagination" role="navigation">
{% if page.previous %}
<a href="{{ site.url }}{{ page.previous.url }}" class="btn" title="{{ page.previous.title }}">Previous article</a>
{% endif %}
{% if page.next %}
<a href="{{ site.url }}{{ page.next.url }}" class="btn" title="{{ page.next.title }}">Next article</a>
{% endif %}
</nav><!-- /.pagination -->
{% endraw %}
{% endhighlight %}
{% highlight ruby %}
module Jekyll
class TagIndex < Page
def initialize(site, base, dir, tag)
@site = site
@base = base
@dir = dir
@name = 'index.html'
self.process(@name)
self.read_yaml(File.join(base, '_layouts'), 'tag_index.html')
self.data['tag'] = tag
tag_title_prefix = site.config['tag_title_prefix'] || 'Tagged: '
tag_title_suffix = site.config['tag_title_suffix'] || '&#8211;'
self.data['title'] = "#{tag_title_prefix}#{tag}"
self.data['description'] = "An archive of posts tagged #{tag}."
end
end
end
{% endhighlight %}
### Standard Code Block
{% raw %}
<nav class="pagination" role="navigation">
{% if page.previous %}
<a href="{{ site.url }}{{ page.previous.url }}" class="btn" title="{{ page.previous.title }}">Previous article</a>
{% endif %}
{% if page.next %}
<a href="{{ site.url }}{{ page.next.url }}" class="btn" title="{{ page.next.title }}">Next article</a>
{% endif %}
</nav><!-- /.pagination -->
{% endraw %}
### Fenced Code Blocks
To modify styling and highlight colors edit `/assets/less/coderay.less` and compile `main.less` with your favorite preprocessor. Or edit `main.css` if that's your thing, the classes you want to modify all begin with `.coderay`. Line numbers and a few other things can be modified in `_config.yml` under `coderay`.
