Hi,
In VS2013 (or possibly a web-essentials add-on), when I choose a class in the html editor there are "normal glyphs" or "bootstrap glyphs". In other words I can instantly see which classes relate to bootstrap. Does anyone know how this can be added for custom css files. so, e.g. I want to add a specific responsive css file and assign all its classes / ids to a custom glyph. Any ideas?
