Twenty Twelve Theme

I recently changed themes from a custom made one, that I’ve used for a long time, to a theme called Twenty Twelve, the current WordPress default theme. I made one slight change though which alters the entire look of the theme. I changed font from the default ‘Open Sans’ to ‘Lato’ which is available from Google. To facilitate the change, I’m using my Webfonts plugin and this CSS code:

#page {font-family:'Lato', sans-serif;}
