Header Dealing with different root path

[rturk]

Hi All,
I'm using this great template inside a existing website, so it's not located in the root folder / it's located in a /university folder.

I'm struggling with the header component, the code below checks for root, in this case / and includes or not additional classes to the Header.

https://github.com/greglobinski/gatsby-starter-hero-blog/blob/master/src/components/Header/Header.js#L27

I was able to partially fix this including the following code:

 const isHomepage = (this.props.path === "/" || this.props.path === "/universidade/") ? "homepage" : "";

It works, but it won't scale, for example, breaks if Google analytics sends utm tag.. etc.. IMO this is not the best solution.

Any ideias for how to improve this?
