# CSS2 RDoc HTML template

This is a template for RDoc that uses XHTML 1.0 Transitional and dictates a bit more of the appearance of the output to cascading stylesheets than the default. It was designed for clean inline code display, and uses DHTMl to toggle the visbility of each method’s source with each click on the ’[source]’ link.
