I am not a programmer. The language is foreign. I am creating a WordPress website. I created a child-theme. 

1. I read the theme documentation. Understood very little.
2. sent an email to the theme owner. No answer (2 weeks ago)
3. searched the web - found many websites - i.e. <http://www.w3schools.com/> - <http://css-tricks.com/sans-serif/> & others - me, no speak the language. Can you place html code in a CSS file?

The child-theme consists of a new `style.css` file. The top section of the `style.css` file is what was needed to create the child-theme. Then there are color changes which I inserted & that has gone very well. 

Changing the font family is confusing. Poking around the parent theme and also using 'Firebug' the font(s) seem(s) to be ('inherited'?). `.genericon`, 'Roboto Condensed', Sans-serif, Arimo, Arial and a few other standard MS Word fonts. I saw on the Google font site a couple of fonts I would prefer to use for my website. 

* How do I (or even can I) download the Google fonts to the Style.css file?
* What do I need to insert in the child style.css file to override the parent fonts?

In case this is important, the theme has more than one template (PHP?) option. I am using W7 OS.
