title: Syntax Highlighting Post
excerpt: "Demo post displaying the various ways of highlighting code in Markdown."

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.[^1]

### Highlighted Code Blocks
### GFM Code Blocks
To modify styling and highlight colors edit `/_sass/syntax.scss`.
GitHub Flavored Markdown [fenced code blocks](https://help.github.com/articles/creating-and-highlighting-code-blocks/) are supported. To modify styling and highlight colors edit `/_sass/syntax.scss`.
{% highlight css %}
```css
#container {
float: left;
margin: 0 -240px 0 0;
width: 100%;
}
{% endhighlight %}
```
{% highlight html %}
{% 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 `/_sass/coderay.scss`. Line numbers and a few other things can be modified in `_config.yml`. Consult [Jekyll's documentation](http://jekyllrb.com/docs/configuration/) for more information.

### Code Blocks in Lists
Indentation matters. Be sure the indent of the code block aligns with the first non-space character after the list item marker (e.g., `1.`). Usually this will mean indenting 3 spaces instead of 4.
1. Do step 1.
2. Now do this:
```ruby
def print_hi(name)
puts "Hi, #{name}"
end
print_hi('Tom')
#=> prints 'Hi, Tom' to STDOUT.
```
3. Now you can do this.
