Change font for <em> and <strong> in CSS?

[kzoll]

Evening all,

Just need some basic CSS help and Google is not being helpful at all. I'm running the latest Genesis + Lifestyle Theme.

I'm looking to import Old Standard TT, a Google Web Font, as the font family for my website. It comes in three weights/styles as seen here: http://www.google.com/webfonts/specimen/Old+Standard+TT

I know how/where in my stylesheet I need to put the import font code - that's no problem. I would like to edit my CSS such that all < em > tags trigger the Normal 400 Italic version of the font and all < strong > tags trigger the Bold 700 version.

Any pointers on how I would do this in my stylesheet?

Thanks so much in advance!
