I have spent a great deal of time creating my custom CSS, and there is not one bit of instruction on how to incorporate the fonts into existing CSS. The statement "Your theme sucks", is moronic and childish to say the least. The developer of this plugin seems to want everyone to scrap their existing CSS and just add the classes that he wants you to use.
Its much easier to just declare the google font in my CSS. This plugin is useless. I wish I could give it less than one star.
