New embed code for asynchronous font loading
Today we’re changing that. From now on, all new kits will asynchronously load fonts. This will significantly improve your website performance. However, it can also cause the browser to render content in a fallback font before your web fonts load. This so-called Flash Of Unstyled Text can be controlled by using the font events provided by Typekit. Using font events, you can choose either to hide your content, or to show fallback fonts while your web fonts are loading.
