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 `/_sass/pygments.less`. {% highlight css %} #container { float: left; margin: 0 -240px 0 0; width: 100%; } {% endhighlight %} Line numbering enabled: {% highlight html linenos %} {% raw %} {% 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'] || '–' self.data['title'] = "#{tag_title_prefix}#{tag}" self.data['description'] = "An archive of posts tagged #{tag}." end end end {% endhighlight %} Remember, to prettify code you need to wrap it in special Liquid tags. Code fenced blocks won't get the job done. For more info on how to highlight code snippes in Jekyll, check the [official docs](http://jekyllrb.com/docs/posts/#highlighting-code-snippets). ### Standard Code Block {% raw %} {% 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`. ~~~ css #container { float: left; margin: 0 -240px 0 0; width: 100%; } ~~~ ~~~ html {% raw %}{% endraw %} ~~~ ~~~ 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'] || '–' self.data['title'] = "#{tag_title_prefix}#{tag}" self.data['description'] = "An archive of posts tagged #{tag}." end end end ~~~ ### GitHub Gist Embed An example of a Gist embed below. {% gist mmistakes/6589546 %}
