Looking for a CSS template that allows me to replicate the look of the documention sites of Google's different APIs

Question

I am making web pages to document how people will use some free mapping software my team is releasing soon. I am not a web page designer, and didnt want to spend too much time getting familiar with CSS, but i still want a clean and professional site.

So after some web surfing research, I realized Google's documentation sites (MAPS API example) are very clean and simple and might be a good model for our site.

Is there a CSS template out that I can use to make something close to Google's Documentation style?
