Translate to PT-BR

I created a pt-br.html file with the translated content.

To CSS work online in gh-pages, I put on CSS link tag a {{ site.url }}. I don't know if this is a good idea, but works fine:
-    <link rel="stylesheet" href="code-guide.css">
+   <link rel="stylesheet" href="{{ site.url }}/code-guide.css">

What you think?
