3. 代码高亮

一个tab或者四个空格：

var Mou = exactlyTheAppIwant

var s = "JavaScript syntax highlighting";
alert(s);

def function():
#indenting works just fine in the fenced code block
s = "Python syntax highlighting"
print s

require 'redcarpet'
markdown = Redcarpet.new("Hello World!")
puts markdown.to_html

@nice-blue: #5B83AD;
@light-blue: @nice-blue + #111;
#header { color: @light-blue; }

No language indicated, so no syntax highlighting.
s = "There is no highlighting for this."
But let's throw in a tag.
