When loading web-fonts, we often see a brief un-styled moment before the browser applies the actual font. Gladly Typekit and also Google Web Fonts provide an option around that.

Both are using WebFont Loaders to help handle those brief moments.

TypeKit Webfont Loader Example

This adds a class name to the <html> element during loading

This is removed when loading is done. This allows us to hide content until all fonts are loaded.

Webfonts Loading

This also adds classes once the webfonts have been loaded, which allows us to add some transitions to reveal the content again.

Webfonts Loaded

One last thing. You should add the webfont loader early in your content, so that it can do its magic before anything else is being loaded.
