This module provides a grunt multi-task injecting content of font files into stylesheets using data URIs. When you develop a HTML5 component, your styling may include special fonts. If the page, which hosts your component has not the same origin, the server has to include the CORS headers in the response with the font file (Access-Control-Allow-Origin: * at least) according to the W3C Font fetching requirements. You should always try to configure the web server to do it to get the best performance. If you cannot, you can embed the fonts in the CSS files by this task, but the size of the base64-encoded fonts for the page to load will be circa 35% greater. Additionally, the browser will load all fonts immediately with the stylesheet, otherwise only the needed font faces and formats would be downloaded.
