This stylesheet provides a common interface to specify icons for transformations to presentation-oreinted formats. This allows similar output for different types of input documents.
Many of the icons are output as SVG elements that can be embedded directly into an HTML document. These icons use class names like yelp-svg-fill and yelp-svg-stroke, allowing you to style them with colors from the colors module.
Some SVG icons are read from separate source SVG files. When this is done, the icons.svg.mode mode is applied to reduce the SVG to the minimal form needed for proper presentation.
