How do you apply an external stylesheet to a textile document with Ruby's Redcloth, so that I can convert it to HTML and it will apply the styles?
I understand how to apply styles individually to parts of text, but how to I define a whole style (say text with font-size 20, color red, alignment x, font-family y, etc.), and apply it to all the h2 tags, without having to copy-paste that {hash} everywhere?
